Reality TV star Kim Kardashian, who will marry rocker Kris Humphries Aug 20, has reportedly asked the wedding guests to wear black or white colours for her marriage.

Kim, who will wear a Vera Wang gown for her marriage, does not want to "blend in" with friends and family at the ceremony.

"Kim knows better than anyone how to stay dramatic and there is no way she would let herself blend in with everyone else at her wedding by wearing a white dress," contactmusic.com quoted a source as saying.

"If I know her, I bet she will wear red or some color so she pops against everyone else who will be in black or white," the source added
