Better to make variables than calling substr twice.

hex.substr(1,1) + hex.substr(1,1) +
hex.substr(2,1) + hex.substr(2,1);
}

return Std.parseInt ("0x" + hex);
}

What do you think about adding unit tests for these two new functions? (This one and parseHex)

{
// CSS2 rgb color definition, matches 0-255 or 0-100%
// e.g. rgb(255,127,0) == rgb(100%,50%,0)

inline function range(val:Float):Int {
// constrain to Int 0-255
if (val < 0) { val = 0; }
if (val > 255) { val = 255; }
return Std.int( val );
}

var r = Std.parseFloat(rgbMatch.matched (1));
if (rgbMatch.matched(2)=='%') { r = r * 255 / 100; }

var g = Std.parseFloat(rgbMatch.matched (3));
if (rgbMatch.matched(4)=='%') { g = g * 255 / 100; }

var b = Std.parseFloat(rgbMatch.matched (5));
if (rgbMatch.matched(6)=='%') { b = b * 255 / 100; }

return ( range(r)<<16 ) | ( range(g)<<8 ) | range(b);
}
