Google Cache Black

... how did it get that?

I have a few hundred pages on one site that are all the same coloured template. There is a table in the centre in two sections which has the top half in red (9b0000) and the bottom half in white (ffffff).

But on the Google cache of that page the entire thing is just a black table. This means that you can't see any of the images or writing in table. Is this how Google "sees" my page? If so, could there be problems for my site if Google is painting a black mark across half the page?
