Simple ways to compare everyday colors

[Emmales]

For a neighborhood clothes swap, I have been asked to prepare some guidance about choosing colors. The event welcomes all ages and a wide range of personal styles. Size labels are straightforward, while grouping donated clothes by flattering colors seems much harder to explain fairly. I want the advice to stay optional and friendly, especially for people who have never considered seasonal palettes. The resource I have been looking at for background is color analysis but I would welcome suggestions about explaining the idea without presenting an online result as a fixed rule. Is a simple scarf comparison a reasonable activity when there is little time for individual advice? The room has large windows, although the available daylight will change as the event goes on. I would appreciate examples of friendly wording that keeps the emphasis on experimenting with clothes people already own.
