I'm thinking about changing my hair color, but I want to understand my undertone first. The camera seems to give me a different answer in every room. In daylight my skin looks fairly neutral, while the bathroom light makes it look much warmer. I suspect the lighting is affecting what I see. I don't want to pick a hair shade based on one misleading picture. Is open shade outside a better place to take the photo? I'm also unsure whether to compare my face with a white shirt, a gray background, or several fabric colors. The usual vein test has not helped me much. I found this page while looking into <a href=https://hair-color.top>skin undertone test camera</a> and plan to use it as a starting point for comparing colors rather than treating one result as a verdict. Has anyone found a simple way to repeat the test without changing the lighting? I can compare the same shirt in each photo. It might help me notice when the lighting shifts. I'd especially appreciate advice from anyone who checked their palette before making a hair appointment. I have time to try a more careful comparison before I book.
