Having spent most of my last two working days implementing a colour picker
:-P I must say I like the idea of hue/saturation; it's perfect for this
purpose, as it completely describes a light colour.  And you can use one
byte, wasting no bits, and have great resolution; 4 bits of hue and 4 of
saturation is pretty good.

Of course, people don't know how to write their favourite colours as
hue/saturation pairs :-) but they can open up the gimp and get the correct
values from the colour picker therein.

best,
