Red lace blazer or blue military jacket?

My brothers wedding is next Friday and I can't decide on a jacket. My dress is a white knee length with ruching over the bust. I'm wearing bronze key shaped earrings and pendant, and bronze bangles.My shoes are dark brown heeled sandals. I have dark brown hair and a really dark tan. My options are a red blazer with lace sides and sleeves or a cobalt blue military style jacket. And yes I'm aware that white is reserved for the bride, but it is her request that the females in the immediate family of herself or my brother wear white dresses if not in the party to be easily distinguished from the other guests.
