How reliable are virtual hair-colour previews?

[Marvincok]

Earlier this week I finally cleared the clothes I never wear from my work wardrobe. I have pale skin, naturally blonde hair, and light blue eyes, so I expected the remaining pieces to work together fairly easily. Instead, anything close to warm beige makes me look much duller, especially under the lights in our office. Colours such as muted greens seem calmer, although I cannot tell whether that is a real pattern or simply preference. A recent photo in a muted teal scarf made the difference noticeable enough that I want a sensible method before buying more clothes. I keep wondering whether I am reacting to the camera on my phone. To organize the possible palettes, I used cool summer hair colors as a helpful way to narrow things down. Now I plan to compare the same two tops in video calls before choosing between navy trousers. I am trying to keep the experiment cheap, repeatable, and practical. Has anyone found one clothing test that stays reliable in different light?
