Red Hot or Cool Blue? Uma Thurman at Cannes 2011.

Uma Turman did color gloriously at the Cannes yesterday, after a long array of whites and pastels.

She was spotted in a delish long pleated dress from Valentino, followed by Roland Mouret gown in blue at the red carpet.

The Valentino was a dressed down look, in glasses and sandals, but I don't know if you can/should do dressed down in a Valentino. The gown on the red carpet had Uma turning up guns blazing, with red lips and sexy, wavy hair.

Loved both the looks. Do you have a favourite?
