I am new to checking undertones without an appointment but my results change more than I expected. Beside a bright window my face reads almost neutral while warm indoor bulbs make it look noticeably golden. My phone also applies automatic white balance even when I keep the same position and background. I kept my face bare and wore a medium-gray shirt so clothing should not be adding much reflected color. I am comparing the photos with a simple [url=https://hairdye.top]skin undertone test camera[/url] rather than trusting one image. Is a fixed exposure and white-balance setting essential before taking a short series of photos? I am able to add both white and neutral-gray references if that makes the comparison more useful. If you have repeated this kind of test, which lighting conditions were consistent, and which clues did you ignore? I am mainly looking for a method that produces the same answer twice before I start choosing hair or clothing colors from the result.
