For a remote style workshop, I need to present several hair color options using a single portrait. I want the comparison to be easy to read without turning it into a vote on the best-looking picture. Every version will use the same framing, since different crops could distract people from the actual color change. While looking into a hair color simulator I started making a checklist of the settings that should stay consistent. All options should share a background and the same overall exposure instead of receiving separate visual touch-ups. I could number the pictures first, allowing people to describe what they notice without a shade name suggesting an answer. The introduction will make clear that a digital preview is a comparison aid rather than a promised salon result. Once everyone has described the pictures, we can reveal the shade labels and compare the wording people used. Are there any obvious controls missing from this plan for presenting hair color alternatives?
