For an accurate color read, take your selfie in indirect daylight near a window, with a bare face, hair pulled back, no filter and a plain background. The photo is the single biggest factor in accuracy — warm indoor light, makeup and beauty filters all rewrite the exact colors the analysis depends on. Re-scan in different light and compare to confirm.
| Do | Don't |
|---|---|
| Indirect window daylight | Warm lamps or overhead light |
| Bare, clean face | Makeup, especially foundation/bronzer |
| Plain neutral wall | Colored walls or busy backgrounds |
| Phone at eye level | Filters / beauty mode / heavy editing |
A good photo is worth more than a fancy algorithm. If your result feels off, re-shoot in better light before assuming the analysis is wrong — and use a tool that reports confidence so you know when the photo wasn't good enough.
If two scans disagree, trust the one shot in better daylight. A good tool will also report its confidence — a low-confidence result usually means the photo was the problem, not your coloring. Re-shoot near a window before assuming the analysis got it wrong.

Indirect natural daylight, like standing a few feet back from a window. Avoid warm indoor bulbs, overhead office lighting, direct sun and colored walls, all of which cast a tint.
Only if it meets the same conditions — daylight, no filter, bare face, hair back, plain background. Most camera-roll photos don't, so a fresh selfie usually gives a more accurate read.
