I am putting together a short community workshop about comparing hair shades, and I want the exercise to stay practical. A mirror and paper samples will be our main materials. The session will involve comparisons without applying dye. One participant asked about cool summer hair colors and I thought that could be a useful example of how people narrow a search. Several brown samples would replace a single perfect example. The labels would describe depth and warmth. We could then discuss why two similar names may look different on different screens or printed cards. I want to leave room for personal preference. Any quiz would simply start the discussion. It would not become a salon formula. Has anyone found a clear way to teach this? I especially want participants to leave with useful questions for a colorist instead of a promise that one shade must suit everyone.
