Celebs attempted to "outbright" one another in a variety of primary and tropical shades at the 2011 CFDA Fashion Awards.

Some of the more notable looks included those of Jessica Alba (who worked her maternity glow in a color-blocked Diane Von Furstenberg gown), Liv Tyler (who was polished to perfection in a puzzle-print Proenza Schouler ensemble) and Chanel Iman (who looked like she'd just come from a St. Tropez model shoot in a turquoise maxi dress and gold sandals).

Also part of the red-carpet rainbow were Emmanuelle Chriqui (who oozed sex appeal in a sunny, bright-yellow mini and multicolored heels) and Alessandra Ambrosio (who radiated in a neon-red gown accessorized with tribal jewelry).

Never one to miss out on a trend, Lady Gaga donned a turquoise wig to fit the occasion.
