Can't oversaturate

[pasz]

I have a sprite with a yellow gradient, which I try to oversaturate, but somehow the effect is way too subtle. Other colors don't have this problem it seems. Is there a line of code I could alter so I can boost saturation even more?

Try this shader

note the properties changed from HSVxxx to HSLxxx
