While we can easily spot things like color (or lack thereof), we were pleased to notice some of the most A-list actresses are sticking to basics. As in primary colors.

Kyra Sedgwick showed off a trim figure in lush red Oscar de la Renta, Anne Hathaway's dramatic blue Armani Privé and Christina Applegate's gossamer yellow Cavalli make a perfect primary trio.

See other reds, yellows and blues from Mad Men's January Jones, Mary Louise Parker, Eva Longoria Parker and Laura Linney.
