I keep hearing about SLW roos having different "Coloring" from the hen

What exactly does that mean? I've seen it mentioned in several of the girl/boy threads, but never an explanation of what the difference in coloring IS between the sexes. A look at feathersite leads me to guess that the Roos are much lighter above, but that's only a guess.

I'm a little worried about one of mine (no sense in posting photos because my latest pics haven't been coloring true, so you'd easily be fooled by the shot) because she's getting a bit red in the comb, but then I heard that that happens a lot with hatchery hens, so I thought I'd look into this coloring thing

I have 14 week old SLW's and the jury is still out. I am pretty sure I have at least 3 roosters of my 7 "pullet" order, but I can't really tell for sure.
