Oh, I really don't know nothing about how and why color modes prefer use HSV or HSL luma , I'm just a digital painter user. The only feedback I can give are with pictures like the previous mail :-)
Btw, you are right , my use of 'superior' word needs to be explain : the color mode in Photoshop ( I used it for years too) don't work nicely with yellow/orange tones painting over gray. You obtain only a muddy green/yellowish tones. That's why I called the Gimp one 'superior' ; because if you use it as a painter to recolor a part and like to use yellow or orange ; the Gimp one will be more efficient for this case. That's why I always prefered the way Gimp handle it than Photoshop.
Just to defend that the two way are usefull :) and I agree and like if you planed to support more then one color model. Good way !  and thanks for the link.

Hmm... this muddy yellowish tone is actually dark yellow i would say :D.
I don't want to annoy you but i just did a little speedpainting (just a hour or so, nothing fancy) in value (grayscale)
and then colored it in yellow with HSL (left) and HSV (right).
I think one can see that the left side preserves the lightness of the image much better then the right side.
This is the reason why the photoshop way is usually preferred.
I know that many of the really great artists paint in value first (to get the contrast between light and dark right at the start) and then they add color. Since i used gimp for years this didn't really work for me because the HSV coloring changes the lightness too much...
It's funny that you actually were annoyed by photoshop and went to gimp.
In contrary i was so annoyed after years of using gimp that i wanted to switch to photoshop ^__^ but then i found krita :D
