Make the blob nucleus more visible

[Houka]

RE: that blob player, that was me and I was not trying to be clever. The guy I was fighting blew out all of the lights and I placed the nucleus just so that I wouldn't die. I do see your point and the nucleus being slightly more visible would be nice in cases where the blob player picks a color that is very difficult to see differences in. White isn't nearly as bad as black, because even when partially lit it's impossible to tell the difference between a nucleus and a thick membrane or other full square blob tile. Players that do this confuse me, because it's also difficult to keep track of where special tiles have been placed in many cases. How do you know when a mitochondria or ribosome needs to be replaced if you can't see where you placed the darn things five minutes later?
