I've been trying to work out my undertone from phone photos, but the answer seems to change with the room. Under warm lamps my skin looks golden; near a window it looks much cooler. I would like a method I can repeat instead of trusting one flattering photo. I could photograph the same spot in steady daylight, with the same camera and no beauty filter. That should at least keep the lighting more consistent. Could a neutral white background make camera color changes easier to notice? I'm uncertain whether makeup would make the comparison less reliable. For a separate appearance check, I found [url=https://findfaceshape.top]color analysis[/url] and thought it might help me frame the comparison without treating a screen result as proof. One picture feels too easy to misread, so I want a few consistent checks. What would you keep constant when repeating an undertone check? I could hold different colored clothes near my face to see what changes. I can repeat the check a week later to see whether the impression holds. I'd appreciate practical steps, especially ways to catch a misleading camera result before buying anything based on it.
