36 ChatGPT Prompts for Color Analysis, Personal and Brand

Color analysis means two almost unrelated things. One is working out which colors suit a particular person. The other is building a palette that works for a brand, an interface or an image. They share a word and very little else, so this page keeps them apart.

The first eleven prompts cover personal coloring and wardrobe. The remaining twenty-five cover brand, design and the checks worth running before a palette goes anywhere near production. All thirty-six work in ChatGPT and any comparable model.

For prompting technique across other kinds of work, see the main ChatGPT prompts guide. Where color is one variable inside a larger image brief, our Gemini prompts for image break that down variable by variable.

• It cannot see your coloring. Skin undertone, contrast level and eye color have to be observed in good natural light. Photographs distort all three through white balance, filters and uncalibrated screens, and a written description is only as good as the judgement you were unsure about in the first place.
• Seasonal color analysis is a framework, not a measurement. It is a useful heuristic used by image consultants, and the four-season, twelve-season and sixteen-season systems disagree with each other. Treat any season a model gives you as one opinion to test against a mirror rather than a result.
• Contrast ratios must be computed, not estimated. A model can propose accessible pairings and can explain the standards, but it should not be trusted to assert that a specific pair passes. Run the actual hex values through a real contrast checker before you rely on the answer.
• A hex value is not a color. The same value looks different across screens, and different again on coated stock, uncoated stock and fabric. Anything heading for print or product needs a physical proof, whatever the palette looked like on your monitor.
• Where it genuinely helps. Explaining why a combination works, generating options faster than you could, naming what you are looking at, and arguing against a palette you have grown attached to. That is a real contribution, and it is what the prompts below are built for.

Six prompts that help you observe rather than be told. None of them asks the model to decide what your season is, because it cannot see you. They give you the tests, the vocabulary and the comparisons so you can decide.

1. Tests you can run yourself

Explain the practical tests used to judge skin undertone and personal contrast level, in enough detail that I can run them myself. For each test, tell me exactly what conditions it needs, what I am looking for, and how reliable it actually is. Include which tests are commonly recommended but not very informative, and say why.

2. The vocabulary, explained

Explain undertone, overtone, value, chroma and contrast as they are used in personal color analysis, with a concrete example of each. Then tell me which of these actually changes which colors suit somebody and which are mostly used to sort people into categories.

3. Interpret my own observations

I have run the tests in daylight and here is what I observed: [describe what you actually saw, including anything ambiguous]. Based only on what I have told you, tell me what that suggests, where my observations conflict, and which single further observation would resolve the conflict. Do not give me a season if the evidence does not support one.

4. Compare the systems

Compare the four-season, twelve-season and sixteen-season color systems. Explain what each one adds, where they disagree with each other, and what somebody with my described coloring would be classified as under each. Be explicit that these are competing frameworks rather than one being correct.

5. Why this shirt works and that one does not

Here are three colors I know look good on me and three I know look wrong: [list them as specifically as you can]. Work backwards and tell me what the good ones have in common, what the bad ones have in common, and what that suggests about which untested colors would work. This is more reliable than any test, so weight it heavily.

6. The colors near your face

Explain why color matters more in garments worn near the face than in trousers or shoes, and what specifically goes wrong when the color is off. Then tell me which garment categories are worth being strict about and which I can wear in any color I like without it mattering.

Prompt 5 is the most reliable one here by a distance. What you already know suits you is real evidence; a season derived from a written self-description is a guess about a guess.

Five prompts for turning an observation into clothes you will actually wear. The useful ones work from what is already in your wardrobe rather than from an ideal palette you would have to buy.

7. Audit what you own

Here is every garment I own in a color worn near my face: [list them with colors]. Sort them into three groups: works well, neutral, and actively wrong. For each item in the third group, tell me whether it could be saved by pairing it with something else or whether it should go. Do not suggest anything new yet.

8. A small palette that works hard

Build me a wardrobe palette of no more than eight colors, given what suits me: [describe]. Specify two neutrals that do the structural work, three colors for garments near the face, two accent colors, and one that only appears in accessories. Explain what each earns its place doing and how many outfits the set produces.

9. The right neutral

Black, navy, charcoal, chocolate, camel, ivory and stone all behave differently against different coloring. Given that [describe what suits me], rank these for me from best to worst near the face, explain what goes wrong with the bottom two, and tell me which one I should buy first if I own none of them.

10. Wearing a color that does not suit you

I love [color] and it does not suit me. Give me four ways to wear it anyway: where to place it, what to put between it and my face, what to pair it with, and which version of it comes closest to working. Be honest if one of the four is not really a solution.

11. Dressing for a specific room

I need to choose what to wear for [describe the occasion, the lighting and who will be there]. Given what suits me, recommend a color combination and explain what it will do under those specific lighting conditions. Include what to avoid because of the light rather than because of my coloring.

Start from prompt 7 rather than prompt 8. A palette built around what you already own costs nothing to adopt; one built from scratch is a shopping list you will not finish.

Eight prompts for color that has to work commercially. The most common failure is a palette chosen for how it looks in a grid of swatches rather than for how it behaves in the places it will actually appear. Our ChatGPT prompts for logos cover the mark itself and ChatGPT prompts for branding the wider identity.

12. A palette with reasons

Propose a brand palette for [describe the business, its customers and what it is competing against]. Give one primary, one secondary, two neutrals and one accent, each as a hex value. For every color, state what job it does and where it appears. Do not justify any choice with a claim about what a color makes people feel unless you can say why that would be true for this specific audience.

13. Separate from the competition

Here are the brand colors of my six closest competitors: [list them]. Identify what the sector has converged on, then propose three palettes that would be distinguishable at a glance in that context. For each, tell me what it gains in distinctiveness and what it gives up by breaking the convention.

14. Where each color is allowed

Here is my palette: [list hex values]. Write the usage rules: which color is the background by default, which is for primary actions, which may never sit next to which, what percentage of a page each should occupy, and what happens when the palette runs out. Write it so a new designer could follow it without asking.

15. Extend it without breaking it

My palette is [list] and I now need colors for success, warning, error and information states. Extend the palette so these read correctly as system states while still belonging to the brand. Tell me which one is hardest to fit and why, and what I should sacrifice if it cannot be made to work.

16. Dark mode from a light palette

Here is my light-mode palette: [list]. Derive a dark-mode version. Explain why simply inverting the values does not work, which colors need their saturation reduced and by roughly how much, and which single color will need replacing entirely rather than adjusting.

17. Survives print and product

My palette is [list] and it needs to work on screen, on coated stock, on uncoated stock and on kraft card. Tell me which colors will shift noticeably on each surface, suggest an adjustment for each that keeps the character, and tell me which single color should be treated as the brand color if only one can be guaranteed.

18. Argue against my palette

Here is the palette I have chosen and why: [describe]. Make the strongest case against it. Cover: where it will be hard to use, what it will look like in six years, which competitor it resembles, and what it will cost to produce consistently. Be direct rather than balanced.

19. Campaign color inside brand rules

I need a distinct color for a campaign that must still read as our brand. Given our palette [list], propose three options, and for each explain how it relates to the existing colors, where it may be used, and where it must not appear so the campaign does not start replacing the brand.

Be sceptical of color psychology claims. Associations vary by culture, context and industry, and a palette justified by what a color supposedly means is usually a palette nobody has tested.

Nine prompts for color inside a composition rather than color as a specification. These are the ones that teach you something transferable, because each asks for the reasoning as well as the answer.

20. Read an image I like

Here is an image whose color I want to understand: [attach or describe it]. Break down the palette: the dominant color and roughly what proportion of the frame it occupies, the supporting colors, the accent, and where the darkest and lightest points sit. Then tell me which single relationship is doing the work, and what would collapse if I changed it.

21. Why this combination works

Here are two colors that look right together and two that look wrong: [give hex values]. Explain the difference in terms of hue relationship, value contrast and saturation contrast rather than in terms of taste. Then give me a rule I could apply to a new pair without asking you.

22. Limit the palette on purpose

Build a palette of exactly three colors plus white for [describe the piece]. For each, give the hex value, the proportion of the composition it should occupy, and what it is for. Explain what a fourth color would add and why it is not worth it here.

23. Grade a photograph

I want to grade a photograph towards [describe the look]. Specify it properly: the hue and saturation to place in the shadows, the midtones and the highlights, the direction to move the white balance, and how far to push each before it becomes obvious. Tell me which of those does most of the work.

24. Color for a period or medium

Describe the characteristic palette of [name a period, printing process or film stock] and explain what technical constraint produced it. Give me hex approximations for five representative colors, and tell me which one is the giveaway that identifies the era to somebody who knows.

25. Where the eye goes

Here is a composition: [describe or attach]. Tell me where color is directing the eye and whether that matches where I want it to go. If it does not, tell me the smallest color change that would redirect it, rather than a redesign.

26. Palette from a photograph

Extract a usable palette from this photograph: [attach or describe]. Give six hex values with the proportion each occupies in the original. Then adjust them into a palette that would work for a digital interface, and explain what you had to change and why the raw extraction would not have worked.

27. One color, many versions

Take [hex value] and build a full tint and shade scale from it with nine steps. Keep the perceived hue consistent across the scale rather than simply mixing with white and black, and explain where naive lightening would have shifted the hue and what you did instead.

28. Test it in the image

Write an image generation prompt that would show my palette [list hex values] applied to [describe a realistic scene or layout], so I can see how the colors behave together in context rather than as swatches. Specify the proportions and where each color appears.

Prompt 28 is worth running on every palette. Colors that look balanced as equal swatches behave completely differently at real proportions, and an AI image generator will show you that in about a minute.

The last eight, and the ones that stop an expensive mistake. Several ask the model to tell you what it cannot verify, which is the correct answer more often than people expect.

29. Accessibility, honestly

Here is my palette: [list hex values]. List every text-on-background pairing I am likely to use and tell me which ones look likely to fail contrast requirements and which look safe. State clearly that these are estimates and that I must verify each pair in a real contrast checker, and tell me which pairings to check first.

30. Color-blind viewers

Here is my palette and here is how I am using it: [describe, including any chart, status indicator or map]. Identify every place where meaning depends on color alone, and for each tell me what secondary signal to add. Tell me specifically which two colors in my palette are most likely to become indistinguishable.

31. Cultural reading

We are launching in [list markets] with this palette: [list]. Tell me where a color or combination might carry a meaning we have not intended in any of those markets, and be explicit about where you are uncertain. Recommend which ones to check with somebody local rather than assuming your answer is current.

32. Behaviour at small size

Tell me how each color in [list] behaves at very small sizes: a 16-pixel icon, a one-pixel rule, thin type. Identify which colors lose their identity when there is not much of them, and what to substitute in those cases.

33. What it will look like in five years

Here is my palette: [list]. Tell me which parts of it are tied to current design fashion and which are structural. For each fashionable element, suggest a more durable alternative that keeps the same character, and tell me how much distinctiveness I would lose by making the swap.

34. The one-color version

Convert my palette [list] to greyscale by perceived lightness and tell me which pairs become identical. Then tell me what that reveals about the palette: if two colors are the same value, they will read as the same in any single-colour reproduction, and that is a structural problem rather than a printing one.

35. What I am not seeing

I have been looking at this palette for two weeks and can no longer judge it: [list]. Tell me the three things somebody seeing it for the first time would notice, including anything unflattering. Then tell me which of my choices looks like it was made for a reason and which looks arbitrary.

36. Document it properly

Turn my final palette into documentation somebody else could follow: hex, RGB and a note on where to source print equivalents; the role of each color; the pairings that are approved and the ones that are forbidden; and the two rules people will break first. Keep it to one page.

Prompt 34 catches a problem nothing else does. Two colors with the same perceived lightness will collapse into one the first time somebody photocopies, engraves or faxes your material, and no amount of hue difference saves them.

Colour is one of the areas where a model will happily produce a confident number it cannot compute, so the useful test is whether it admits that. Ask any model the contrast question in prompt 29 and watch whether it hedges appropriately or invents a ratio - that tells you more about whether to trust it here than any comparison would. Browsing the full model list once is worth it, because for palette generation the differences are small and for verification you should be using a real tool either way.

Paste hex values rather than color names. Warm grey means a hundred different things and the model will pick one of them; #8A8578 means exactly one thing and every answer that follows is about the color you actually have. Chat Smith is free to try.

And the check that outranks every prompt on this page: look at the thing in the place it will live. A palette on a screen in a dark room and the same palette on a shelf in a shop are two different palettes, and only one of them is the one your customers will see.
