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. There will be no hair coloring during the workshop. One participant asked about cool summer hair colors and I thought that could be a useful example of how people narrow a search. My plan is to compare a few browns side by side. Warmth and depth would be the main label terms. 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 determine a dye mixture. What simple demonstration would you suggest? I especially want participants to leave with useful questions for a colorist instead of a promise that one shade must suit everyone.
