I have been playing with graphics since Photoshop 2.5SE. I have seen
HSV and other color spaces talks about, conversions and just about
everything. But I have yet to come across other than RGB in any primary
application.
Can anyone who uses other than RGB tell me where you use it and why?

I'm not using HSL/HSB very often, but it's useful, if you want to change the
hue and keep the brightness of the color or the other way round.
Somehow it's more the way you would deal with colors in real-life.

I recently worked in in colour-laser-copy burue, so for me real life colours
are always Cyan-Magenta-Yellow... cool job really, I miss it.

Which begs the question, what the hell is a "burue"?

HSV is more conceptually similar to how artists select, mix, and use
colors (select the hue, assuming no actual color mixing is necessary,
and add white and/or black as necessary).
CYMK is what's used for printing in most cases.

CIE-lab L,a,b and dE for colour matching in making "in mass coloured"
plastics and for mixing printing ink colours. It's the only ISO
standarized method for colour measurement and specification.

I work primarily in RGB, but if I'm planning on printing anything out,
then I either start off in CMYK, or I convert it into CMYK and then
adjust levels and curves to make it look right when it comes out of the
printer.
<rambling>Which reminds me, I really need to get round to setting up an
action in Photoshop to do appropriate adjustments to scans and images
about to be printed...</rambling>
Bye for now,

HSL is used, indirectly, in most windows applications.
If you run windows, bring up the Display window in the Control Panel. Try
choosing a custom colour, anywhere. The window which is presented has the hues
running left to right, the saturation running top to bottom, and the lightness
in a slider on the right.
Choosing HSL manually is ackward, but it's the easiest to grasp visually.
Imagine the same screen with red running left to right, green top to bottom, and
a seperate slider for blue. No one would ever find the colour they want!

CMYK is used in printing. Lab is gamut-free and is widely used in
scientific applications. HSB is used by many artists because it's more
natural (make this color warmer, no honey it's too dark, hush it's
screaming etc.) LUV (or YUV) is used in JPEG and MPEG compression.
These are the ones I can come up with off the top of my head.

Almost as useful as <sarcasm> and </sarcasm> when dealing with people
who's grasp of the concept you are unsure of... <grin>

Oops, that should, of course, have been "whose".
