Hi
Don't forget there's always the Expand option (right click) to get a color picker where you can adjust saturation and color in the circle and brightness with a slider. But that's no HSV.
It sortof works for me as a color _assigner_, but it doesn't allow me to easily do color _modifications_ in HSV space. Heck, two simple RGB2HSV and HSV2RGB VSL math _operators_ with one input (same output, or as duo with input/output) would have been nice too. This should be fairly easy to implement as well for development team as the formulas are already out there.
Maybe something for plugin developers?
It's also a matter of lack of human color sensitivity why graphics are often oversaturated. Grass is green [0 255 0], the sky is blue [0 0 255] and roses are red [255 0 0]. Not so! People just don't pay attention to all the nuances...
Color is not absolute by a longshot. It's a perception thing more than anything else. One color look different depending on what color it is viewed next to. Timo showed a brilliant example of this on IRC a while back. Anyone still got that link?
"Working with color" by Lynda.com is an amazing tutorial I reccomend. Value is by far the most prominent channel that tells color, not hue or saturation. Just isolate any picture in Photoshop as HSV channels and see which is the most varied.
At the moment I'm still occupied with landscapes (and lately volumetric skies again), I'll see if I can apply HSV for that. Indeed I sometimes notice yellowish over-saturation in brightly lit areas, maybe RGB is causing this?
Oversaturation is usually an artist interpretion error. Make any object as you think it is. Take a photo of the same object and compare them in Photoshop. You'll probably be amazed how strong your own colors are compared to the photo. Any brightness overboost will naturally cause oversaturation even more.
I think RGB is sufficient for a graphics program to "work with", but modifying in other colorspaces has its uses, especially HSV.
