Color suggestions? music video about a young girl who died tragically of cancer

I'm making a music video about a 16 year old girl who died of cancer, but was very inspiring

I have footage of this girl's life, which I want to show in the music video, and I want something that will distinguish the home videos of the girl, from the other clips in the video. I'm thinking of placing pieces of home videos in sporadically so its like their remembering her.

The rest of the video is of a band playing on a stage with pictures of the girl, hanging on string from the ceiling. Candles are placed around, and there are a lot of macro shots. Any suggestions for color settings of the live band?

Is Color a good program for light leaks? how do I do those?

Thanks
