Change colour of Facebook Likes/Comments

Hi

I’ve installed the plug no problem and it works a treat.

Only thing I need to do is change the colour of the blue Likes and Comments as it’s too dark for my theme.

I added .rfbp-like-count, .rfbp-comment-count{ color: white } to my Themes style CSS but it hasn’t made any difference.

I’m sure it’s something small and daft but can you tell me how to change?
