Broken: 2.71 (hash: 9337574)
Worked: all versions prior to 2.71
Short description of error
The color picker in 2.71 seems to apply color management to values that should be in linear space.
Exact steps for others to reproduce the error
- open the color picker from a node in the node editor
- under RGB selection set the values to 0.5
- switch to HSV and note that the value field reads 0.735 ( ~0.5**(1/2.2) )
- compare to the behavior of previous versions
The value listed under HSV after following those steps should be 0.5, as color for materials and the compositor should be in linear space. Blender 2.71 is incorrectly applying the display color management to these values; this can be seen by changing the 'Display Device' setting in the Scene / Color Management panel and looking at the HSV value field again.
