Color is important in selecting breeches for competition. Sanctioning organizations and tradition both dictate that show clothing is to be quiet, classic and conservative in design. White is common in dressage, and is also seen in show jumping. Beige is seen in most hunt seat-style equestrian disciplines, though light grays, "canary" (a dull yellow), rust, tan, and an olive-greenish colour are periodically popular with hunt seat competitors. Eventers wear classic colours for the dressage and stadium phase, but less classic colours may be seen on the cross-country course (especially at the lower levels) to match the "stable colours" of the rider. Saddle seat riders, whose riding clothing styles derived from men's business suits, wear Kentucky jodhpurs in dark colors, usually black, navy blue, or a shade that matches the riding coat.
