Warm, cool,
or somewhere between?
A photograph can give a color clue. Light has a say, too.
Your photos never leave your browser.
Start with a photo
Use indirect daylight, without filters or strong color casts.
Select three evenly lit skin areas. With a keyboard, focus the image, use the arrow keys to move and press Enter to sample. Shift moves farther.
Three patches.
One cautious clue.
- Choose a clear photo with even, neutral light.
- Select three skin areas, avoiding lips, blush, shadows and glare.
- Read the photographed color estimate, then compare it with a fabric test.

This measures pixels, not biological undertone or a season. White balance, makeup and reflected light can outweigh the clue.
Start with a fabric test
Compare warm peach and cool rose at a similar depth beside your face. Use a mirror in indirect daylight and repeat the pair. Which combination feels more balanced?
Then compare ivory with a cooler off-white. Keep fabric texture, size and finish consistent.
Read the manual undertone guideSupporting clues
Gold and silver can be another comparison when the pieces have similar shine and size. Vein color is a weak, lighting-dependent clue. Neither can settle a season by itself.
Do not use sun exposure as a test. How skin reacts to the sun does not decide a seasonal palette.
Gather temperature, depth and clarity cluesWhat the sampler calculates
Each patch averages a small square of pixels from the selected area. We convert those three averages from sRGB to CIELAB with a D65 reference white, then compare their mean yellow–blue coordinate with their red–green coordinate. If the patches disagree strongly, the tool asks for a more consistent photo.
The thresholds are an exploratory heuristic, not a validated personal analysis. Read the exact method.
