Free color analysis from one selfie: your exact season, palette and hex codes (ChatGPT)

Hey, it's Cindy ๐ŸŒฑ This is the full pack: the colour read from the reel, then seven more prompts that use the same photo, plus five bonus ones. Start with the photo section, because every prompt below is only as good as the selfie you feed it.

do this first

Take the photo properly ๐Ÿ“ธ

This is the part that decides whether any of it works, and it takes two minutes. Your phone is quietly working against you here, so you're setting up conditions where it can't.

  1. ๐ŸŒค Indirect daylight, mid-morning to early afternoon Stand near a window that doesn't have sun streaming through it, or go outside under cloud. Avoid direct sun, and avoid golden hour, because warm light will push your read warm no matter what your skin is actually doing.
  2. โฌœ๏ธ Neutral everything around your face Plain wall behind you, and drape something white or grey over your top. Colour bounces off whatever is near your face and lands on your skin, which is the exact effect professional analysts use drapes to control.
  3. ๐Ÿ’„ Bare face, hair back, no coloured contacts Foundation and bronzer paint over the thing you're trying to measure, and dyed hair near your jaw contaminates the read.
  4. ๐Ÿ“ต Flash off, HDR off, beauty mode off On Samsung that's Camera then Filters then turn off the face smoothing. On Huawei, switch off Master AI. Worth knowing that on iPhone some skin smoothing is baked into the camera pipeline and cannot be switched off at all, so expect a little of it regardless.
  5. ๐Ÿ“ค Send the original file Straight from your camera roll. Don't screenshot it and don't send it to yourself first, because every re-save throws away more colour data.
๐Ÿ“„ One trick that costs nothing. Hold a plain sheet of white printer paper next to your face, in shot. It gives the model a known neutral to judge the lighting against, which is the same idea as the grey card photographers use to correct white balance.

the main one

The colour read ๐ŸŽจ

The version in the reel asked for everything at once, and that's actually the thing that hurts it most. So this one makes it show its working first, then reach a conclusion, and it asks for two candidate seasons rather than one, because a single confident answer from one photo is usually false precision.

๐ŸŽจ the colour analyst
Act as an experienced personal colour analyst. I've attached an unfiltered natural-light photo of myself. Work through this in order, and do not name a season until the last step.

1. DESCRIBE WHAT YOU SEE. Only what's actually visible: the depth of my skin, the depth and tone of my hair, and my eye colour including any secondary tones in the iris.

2. UNDERTONE. Warm, cool, neutral-warm, neutral-cool or true neutral. Name the specific visual cues that took you there, like how my skin reads against the whites of my eyes or against anything white in the frame.

3. VALUE. How light or deep my overall colouring is.

4. CONTRAST. The gap between my hair, skin and eyes, as low, medium or high. This matters as much as undertone and almost nobody talks about it.

5. CHROMA. Whether my colouring is bright and clear or soft and muted.

6. SEASON. Only now, give me my two most likely seasons from the 12-season system, most likely first, and tell me exactly which of the above would settle it between them.

Then: tell me plainly what you could NOT determine from this photo, and whether anything in the lighting made this harder. Do not flatter me and do not soften a conclusion to be nice.
๐Ÿ’ก the palette, with hex codes
Using that reading, give me two lists with real hex codes, because colour names alone are useless when I'm shopping.

First, 15 colours that flatter me, grouped into my neutrals to build a wardrobe on, my power colours for near my face, and my accents for small doses. For each one give the name, the hex code, and one line on why it works with my undertone and contrast.

Second, 8 colours that work against me. Name each one, give the hex code, and say precisely what it does to my face, whether that's dulling my skin, pulling out redness, or flattening my features by sitting too close to my own contrast level.

Then add the practical bit: if I already own a lot of something on that second list, tell me how to keep wearing it. Away from my face, on my lower half, or with something flattering layered at the neckline.

seven more, same photo

The rest of the cast ๐ŸŽญ

Run these in the same chat so they inherit your colour read. Each one is a different specialist looking at the same face.

1 ยท ๐Ÿ’‡โ€โ™€๏ธ the colourist
Act as a professional hair colourist. Using my colouring from above, work out what hair colour actually suits me.

Start by identifying my natural depth on the professional level scale, 1 being black and 10 being the lightest blonde, and tell me what you're basing that on. Then name my underlying pigment, since levels 1 to 4 pull red, 5 to 6 pull orange, and 7 to 10 pull yellow when lifted. That's what decides how a colour turns out on me, not the picture on the box.

Then give me three directions: one that's a subtle shift from where I am now, one that's a bigger change, and one you'd talk me out of, with the reason. For each, give the depth level, the tone or reflect (ash, gold, copper, neutral, violet), and what it would do to my skin.

Finally, tell me what to actually say to a colourist so I don't get something different from what I meant.
2 ยท ๐Ÿ’„ the makeup artist
Act as a makeup artist. Using my undertone and depth, build me a palette I can actually shop for.

Give me my foundation undertone in the language brands use, then blush, lip for everyday and lip for bold, eyeshadow tones, and eyeliner. For each one give the shade family, a hex code where it helps me picture it, and why it works on me.

Then the useful half: name the shades that fight my colouring and say what they do, so I stop buying them. And tell me the one shade in my palette that will do the most work if I only buy a single thing.
3 ยท ๐Ÿ’ the jeweller
Act as a jeweller. Tell me which metals suit my colouring, but go past the gold-versus-silver binary, because that's a starting point rather than a rule.

Cover the default my undertone points to and why, then how finish changes it, since matte, brushed and polished versions of the same metal reflect differently against skin. Tell me whether I can wear the other metal too, and under what conditions. Then cover rose gold and mixed metals, and which stone colours sit well against my colouring.

Be specific about where it matters most, because a ring is a long way from my face and earrings are not.
4 ยท โœ‚๏ธ the hairdresser
Act as a hairdresser. From my photo, read my face shape and my hair texture, whether it's straight, wavy, curly or coily, and how fine or thick it looks.

Then give me three cuts that would work, and for each one explain what it's doing: where it adds width, where it takes it away, where the shortest point sits, and how much upkeep it needs in weeks between trims.

Also tell me one cut that gets recommended for my face shape that you'd actually avoid given my texture, because texture overrules face shape more often than people admit.
5 ยท ๐Ÿ‘” the tailor
Act as a stylist working on necklines. Using my face shape, jawline and neck length from the photo, tell me which necklines and collars work on me and which fight me.

Cover crew, scoop, V, square, boat, turtleneck, collared shirt and open collar. For each, say what it does to my proportions rather than just yes or no.

Then give me the three I should default to, and the one I should be careful with plus how to make it work anyway, whether that's with a necklace, a layer, or an open button.
6 ยท โœ๏ธ the brow artist
Act as a brow specialist. Look at my current brow shape, my face shape and my brow's natural thickness and direction.

Tell me where my arch currently sits and where it would sit better, how much of the tail is working, and whether my brows are too close together or too far apart for my features. Give me the shape I should be growing toward and roughly how long that takes.

Then tell me what to ask for, and what to say I do NOT want, since that second part is what stops a brow appointment going wrong.
7 ยท ๐Ÿ‘“ the optician
Act as an eyewear stylist. From my face shape, brow line and the width of my face, recommend three frame shapes that would suit me and one to avoid, and explain what each one does to my proportions.

Cover shape, but also frame width relative to my face, where the top bar should sit against my brows, and whether metal or acetate suits my colouring better given my undertone.

Then tell me the two measurements I should actually check on a listing so I can buy online without trying them on.

five bonus

The bonus five ๐ŸŽ

1 ยท ๐Ÿ› the shopper
Turn my palette into something I can type into a search bar, because no retailer labels anything by hex code.

For each of my main shades, give me three to five colour names shops actually use for that family, like the difference between camel, tan, biscuit and toffee, and flag which of those tend to run warmer or cooler so I know which listing to trust.

Then tell me the three shades to buy first if I only have budget for three pieces, and why those three. Finish with what to watch for when buying online: how studio lighting distorts a product photo, which fabrics shift a colour's warmth, and how to sanity check a listing against my palette before I buy.
2 ยท ๐Ÿงฅ the wardrobe editor
I'm going to describe or photograph what's already in my wardrobe. Audit it against my palette.

Sort what I own into three piles: keep and wear near my face, keep but move away from my face, and stop buying more of this. For anything in the second pile, tell me how to make it work rather than telling me to get rid of it.

Then find my gaps. Tell me what my wardrobe is missing to make the pieces I already own work harder, and give me a shopping list of no more than five items in specific shades.
3 ยท ๐Ÿ“ธ the photographer
Using my palette, tell me exactly what to wear when I'm being photographed.

Cover my most flattering colours near my face, which to keep well away from it, what backgrounds make me stand out rather than disappear, and which of my shades photograph badly under indoor or artificial light even though they look fine in person.

Then give me three complete outfit colour combinations I can default to, one casual, one smart, one for an event.
4 ยท ๐Ÿง  the tutor
Now teach me the logic, so I can judge a colour myself without asking you again.

Explain the three things that decide whether a colour suits someone: undertone, value, and chroma. For each one, tell me what mine is, what happens visually when a garment matches it, and what happens when it clashes. Plain language, not industry jargon.

Then give me a three-question test I can run in my head in a shop that gets me to yes or no on any garment in under ten seconds.

Then quiz me. Name six colours one at a time, wait for my answer each time, and tell me what I got right and what I missed. Make at least two of them close calls rather than obvious ones.
5 ยท ๐Ÿ” the second opinion
Now argue against your own reading.

Make the strongest possible case that I'm actually the second season you named rather than the first. What in the photo supports that? What did you weight too heavily the first time?

Then tell me the single cheapest test I could do in real life to settle it myself, using something I probably already own, and tell me exactly what I'd be looking for when I do it.

the honest bit

What this can and cannot tell you โœ…

Worth knowing before you take any of it as gospel. Colour is genuinely the weakest thing these models do with an image. In one published study testing GPT-4V on interpreting figures, colour perception scored under 60%, while things like recognising a chart type scored 85 to 100%. And nearly 78% of its wrong colour answers were wrong the same way every time, so re-running the prompt won't shake the error out.

โœ… Reliable enough for Narrowing the field. Ruling out clearly wrong directions, getting the broad warm or cool call, and giving you vocabulary for what you're looking at.
โš ๏ธ Not reliable for A definitive season. That's why the prompt asks for two, and why the last bonus prompt makes it argue against itself.
๐ŸŽฏ Treat it as A hypothesis to test, not a verdict. Hold real fabric up next to your face in daylight and see which one wins. That's what professionals do, and it costs nothing.
๐Ÿงช Where it's strongest Hair depth and tone, because the level system is genuinely standardised, and anything about proportion like necklines and frames.

One more piece of honesty about the framework itself. The measurable parts, undertone, value and chroma, come from a real colour system. The season labels on top are a styling convention that grew out of mid-century colour teaching and the fashion industry, not a lab-validated diagnosis. That doesn't make them useless, they're genuinely handy shorthand, it just means nobody can be scientifically wrong about your season.


before you upload

Your face is data ๐Ÿ”’

๐Ÿ”’ Three things worth doing before you upload a photo of yourself. Turn off "improve the model for everyone" in Settings then Data Controls if you'd rather your face wasn't used for training, and know that switching it off stops future use rather than deleting what's already gone. Your uploaded image also lands in your file library separately from the chat, so deleting the conversation does not delete the photo, you have to remove it there too. And only ever upload your own face, or someone's who has actually said yes.
