I think they chose the colour Red for a few reasons.
The first, as others have mentioned. Who doesn't like the look of a shiny red ferrari. The colour Red definitely stands out and I think it looks quite nice.
The second reason could be related to their charity. It's all about aids and creating a aids free generation. So that's got to do with blood and red would be a appropriate colour.
