Ashley tells us:
I have submitted it in a few different colors to show options. If I had my choice I'd probably pick the process blue and red. The "visited" color scheme is meant to evoke old-school link colors, even if subconsciously. The "hot" color scheme is for fun. I like it but I think it's not what the Perl community at large would go for. Black to show what it would look like on printed flyer or black and white business card or such. If only one is to be displayed, I'd pick the blue and red with the notice, if possible, that color scheme could certainly be voted upon.
One reason I like this design is it lends itself to a nice shorthand:
}cpan. Easy to IRC, note, etc.
