Get a full color analysis with Claude, from one photo

Hey, it's Cindy ๐ŸŒฑ You commented COLORS, so here is the whole sequence: the exact undertone prompt, the yes-list and no-list prompt, the ten-shade capsule palette with real hex codes.

A studio colour analysis is a genuinely good service and a genuinely expensive one. TIME reported that a three-hour session at House of Colour in Brooklyn runs about 545 US dollars, while studios in Seoul, where the trend exploded, sit closer to 80 to 160 dollars (TIME, 2023). What you are paying for is a trained eye, controlled lighting, and fabric drapes held against your face.

You cannot fully replicate the drapes at home. What you can do is get the reasoning: your undertone, the colours that fight it, a palette with hex codes, and the logic behind all of it, from one photo and a chat.

๐Ÿ‘ฉโ€๐Ÿ’ป The honest version of what this is. Claude reads your photo, so the answer is only as good as the photo. Phone cameras auto-correct white balance, indoor bulbs push everything warm, and filters wreck this completely. Treat the result as a strong starting hypothesis you then test in daylight, not a lab measurement. Claude also does not generate images of you, so this gives you words, hex codes and a swatch card rather than a rendered magazine report.

do this first

Take the photo properly

This step decides everything. Five minutes here beats any prompt tweaking later.

  1. ๐ŸŒค๏ธ Daylight, indirect. Stand facing a window on an overcast day, or in open shade outdoors. Direct sun blows out your skin and warm indoor bulbs make everyone look golden, which is the single most common reason these readings come back wrong.
  2. ๐Ÿšซ No filter, no beauty mode. Turn off smoothing and any auto-enhance in your camera app. Most phone front cameras apply something by default, so check. Minimal makeup, and none on the lips if you can manage it.
  3. ๐Ÿ‘• Wear plain white or off-white. A strong coloured top bounces colour onto your jaw and contaminates the read. Push your hair back off your face so your natural hair colour, your eyes, and your skin are all visible.
  4. ๐ŸŽจ Add a reference, if you want the good version. Hold a plain sheet of white printer paper next to your face in the shot. It gives Claude a known neutral to judge your skin against, which is the closest thing to white-balancing the photo yourself.
  5. ๐Ÿ“ค Upload it big. In the chat, use the attach button and pick the photo. Anthropic's own guidance is to use images around 1000 by 1000 pixels or larger and avoid small low-resolution ones (uploading files to Claude).
๐Ÿ’ก Take three photos, not one: window light, open shade outdoors, and one more from a different day. Upload all three in the same message and ask Claude to reconcile them. Agreement across three lighting conditions is far more trustworthy than one lucky shot.

prompt one

The undertone read

Attach your photo, paste this, send. This is the prompt from the reel.

๐ŸŽจ read my undertone
I have attached a natural-light photo of myself with no filter. Act as an experienced personal colour analyst and read my colouring from it.

Work through it out loud in this order before you conclude anything. First describe what you can actually see: the apparent depth of my skin (light, medium, deep), the apparent depth and tone of my hair, and my eye colour including any secondary tones in the iris. Second, assess my undertone as warm, cool, neutral-warm, neutral-cool or true neutral, and tell me which specific visual cues led you there, for example how my skin sits against the whites of my eyes or against anything white in the frame. Third, assess my contrast level, meaning the difference between my hair, skin and eyes, as low, medium or high, since that matters as much as undertone and almost nobody mentions it. Fourth, give me your best single seasonal category using the twelve-season system, and name your second-best alternative.

Be honest about confidence: tell me how sure you are out of 10, name anything in the photo that made this harder such as lighting cast or shadows, and tell me what a better photo would need. Do not flatter me and do not soften a conclusion to be nice.

prompt two

The yes-list and the no-list, with hex codes

Send this next in the same chat so it keeps everything it just worked out.

๐Ÿ’ก what flatters me, what does not
Based on that reading, give me two lists with real hex codes so I can match shades exactly rather than guessing from a colour name.

The first list is 15 colours that flatter me, grouped into three sections: my neutrals (the colours I should build a wardrobe base from), my power colours (what I wear near my face when it matters), and my accents (small doses, bags, scarves, lips). For every single colour give me the common name, the hex code, and one short line saying why it works with my undertone and contrast.

The second list is 8 colours that work against me. For each one, name it, give the hex code, and say precisely what it does to my face, for example dulls my skin, brings out redness, or flattens my features by matching my contrast level too closely. Then add one line I will actually remember: if I already own a lot of one of those colours, tell me how to keep wearing it, whether that is away from my face, as a lower half, or with a flattering colour layered at the neckline.

prompt three

The ten-shade capsule palette, as a swatch card you keep

A list of hex codes in a chat is easy to lose. Claude can build you a small page showing the actual colours, which you screenshot and keep in your camera roll for shopping. This works because Claude can produce artifacts, small live pages inside the chat (what artifacts are).

๐Ÿง  build my palette card
Now narrow everything down to a ten-shade capsule palette: the smallest set of colours that would let me get dressed every day and have everything work together.

Choose them with a working wardrobe in mind, so roughly four neutrals I can build outfits on, three mid-tones that pair with everything, two power colours for near my face, and one accent. For each shade give the name, the hex code, what garment it should be (for example "the coat", "the everyday knit", "the going-out top"), and what it pairs with from the other nine.

Then build me a single-page artifact that displays these ten shades as large labelled swatches on a plain background, with the name and the hex code under each one, and the garment role in smaller text below that. Make it look calm and readable on a phone screen, because I am going to screenshot it and open it while I am shopping.
๐Ÿ’ก Then test it in real life. Take the screenshot to a shop, hold a garment right up under your jaw in daylight near the door, and look at your face rather than the fabric. If your under-eyes look softer and your skin looks even, that shade is yours. If your face looks tired and the garment looks great on its own, it is not.

prompt four

The shopping list that uses real search terms

Hex codes are useless in a search bar. Shops name colours their own way, and this prompt translates your palette into the words retailers actually use.

๐Ÿ›๏ธ turn my palette into search terms
Turn my ten-shade palette into a shopping list I can use in a search bar, because retailers never label anything by hex code.

For each of the ten shades, give me three to five real colour names that shops commonly use for that exact family, for example the difference between "camel", "tan", "biscuit" and "toffee", and flag which of those names tend to run warmer or cooler so I know which listing to trust. Then tell me the three shades I should buy first if I only have budget for three items, and say why those three, given what I already need to wear.

Finish with a short checklist of what to watch for when buying online: what to do about photos taken under studio lighting, which fabrics shift a colour's warmth (for example how the same shade reads on linen versus satin), and how to sanity check a listing colour against my palette before I add it to a cart.

prompt five

The part most people skip: learn the why

Every prompt above hands you an answer. This one hands you the skill, which is what the studios are really selling. Once you can explain why a colour works on you, you never need a palette card in front of a rack again.

๐Ÿง  teach me the logic
Now teach me the reasoning behind everything you just told me, so I can judge any colour myself without asking you again.

Explain the three variables that actually decide whether a colour suits someone: undertone, value (how light or dark the colour is), and chroma or saturation (how muted or clear it is). For each variable, explain what mine is, what happens visually when a garment matches it, and what happens when it clashes, in plain language rather than industry jargon. Then give me a three-question test I can run in my head in a shop, in order, that gets me to a yes or no on any garment in under ten seconds.

Then quiz me. Name six specific colours one at a time, wait for my answer each time, and tell me whether I got it right and what I missed in my reasoning. Include at least two that are close calls rather than obvious, because those are the ones I keep getting wrong.

bonus

Two extras worth running

๐Ÿ‘• The wardrobe audit Photograph your open wardrobe in daylight and upload it with your palette. Ask Claude to sort what you own into keep, wear away from the face, and let go, with a reason for each. It turns the palette into decisions instead of theory.
๐Ÿ’Œ The gaps list Ask for the five specific items missing between what you own and the ten-shade capsule, in priority order, with a realistic price range for each. This is what stops a colour analysis turning into a shopping spree.
๐ŸŒฑ Where this genuinely stops. Seasonal colour analysis is a styling framework, not science, and reasonable analysts disagree about the same face. Claude reads pixels, not the light bouncing off fabric under your chin, so the drape test in a studio will always be more accurate. If the result feels wrong when you hold the colours up in daylight, trust your eyes, tell Claude what you saw, and ask it to revise. That conversation is free, and it is exactly how a good analyst works too.
