What are the least-used flag colors?

Answer by  Grace (128)

The least used flag colors are purple, brown and gray because it is hard for other colors to go well with it and match each other along with that color.

All shades of pink are unusual because they are considered feminine. Flags are not "supposed" to be feminine. They are supposed to show strength and masculine virtues.

Magenta isn't used that often. Brown is also rare in flags. I think bright purple is rarly used in flags.
