Description Elle Stone 2012-11-19 17:08:35 UTC 
The krita specific color selector 32-bit floating point Lab sliders don't work. You can move the L, a, and b sliders back and forth, but the sliders themselves remain black, and the only color you can "select" is solid black.

Reproducible: Always

Steps to Reproduce:
1.Open the specific color selector docker.
2.Select Model L a* b*, Depth 32 Bits Float, Profile Lab identity built-in
3.Move the Lightness, a* or b* sliders up and down.
Actual Results:  
The numbers change and the sliders move, but the colors of the bars remains solid black and the actual color selected also remains black.

Expected Results:  
The selected color ought to change to correspond to the selected L, a*, and b* values. And the bars ought to change color also.

I compiled krita and karbon (but not the rest of calligra) from git master on Nov-15-2012.

Hi Elle,

Thanks for your report. I can confirm the issue. I haven't got a fix though -- it needs more investigation.

Doesn't work on CMYK either.
More tellingly both only have 8bit, 16bit, and 32bit float. What happened to 16bit float in both?
