Gabrielle Union is on a colorful style streak, rocking two bright looks in two days.

The actress, 39, stole the spotlight in a low-cut canary yellow Bill Blass gown at the Think Like a Man premiere in Atlanta on Tuesday. She accessorized the bright dress with Gianvito Rossi heels, a Judith Leiber clutch, Liv Haley "Kate" ring, Giles & Brother and Caleo cuffs.

She chose a plunging red look and strappy black sandals with a sleek hairstyle for a screening of the flick, which also stars Selita Ebanks, La LaAnthony and Regina Hall, in New York City on Wednesday.

Union has also been promoting her upcoming indie film, In Our Nature, where she plays the new younger girlfriend of a middle-aged man (Mad Men's John Slattery) struggling to reconnect with his son.
