so what about black & white? what are their strong points?
Black as a background colour lends itself as a perfect contrast to bright colours, particulary red. But to make red stand out, you need a more neutral colour for everything else. That is where white comes in.
White can be used for the bulk of the texts and red for those few words you want to put the focus on. Black as a background, makes both nice and clear and jump from the page!
