Plugs are cheap...if you think they're not cool, replace them.

Those are looking kinda ugly,man. Have you done something different like changed your mixture or added something to the gas?

MTBE in gas causes that dark reddish color.  It's perfectly normal. 

I wish my left plug was that color because I recently got my left cylinder running right, and it's still black because I haven't replaced them yet.

Color looks fine.  Can't tell from the fuzzy photo, but it looks like it's going to be time to replace them soon.
