I'd like to represent strings as arbitrary html colors. Example: "blah blah" = #FFCC00 "foo foo 2" = #565656 It doesn't matter what the actual color code is, so long as it's a valid hexadecimal HTML color code and the whole spectrum is fairly well represented. I guess the first step would be to do an MD5 on the string and then someho...

I'm using cucumber to run some tests. It colorizes its output using ANSI escapes. This is great, but currently its producing more output than I care about, and shoving things I do care about off the screen.
