What is the most flattering colour for show breeches?

Clic attire is beige, tan, khaki or close to it. Dark colors are for schooling at home or just riding. They are not proper for the show ring. Your coat will cover the top of your breeches and your boots will cover the bottom. Not much shows in between, but it should be the proper color. Judges are professionals and being correct makes the right impression on them. Find a style that is flattering, but stay with the correct color.
