Choosing portrait backgrounds for a varied team

Liamml

Our library is hosting a small clothing swap, and I am preparing an optional discussion about choosing colors from the available donations. The activity should stay accessible to visitors with no previous interest in fashion. Participants will bring very different styles, and many simply need something comfortable that fits. I hope a brief conversation could encourage people to try something outside their usual choices. Someone proposed seasonal signs for the tables, although the categories may confuse new visitors. For background, I have been reading about personal color analysis and would like to introduce the vocabulary without presenting it as a set of rules. Visitors can use the mirrors, but volunteers will not be assigning anyone a personal season. I am considering a short prompt about comparing two colors and describing the difference. How would you phrase an invitation that encourages experimentation while respecting each person's preferences?
