Hi,
I have used Lch color space which is calculated from Lab color space
(c=sqrt(a^2 + b^2), h=arctan(a,b)). In this color space L is the
luminance, h the hue (an angle) and c the cromaticy. Color brown might
be always a problem, however, possibly the hue and the cromaticy help
to order the colors.
Regards
Karsten
