Got a break today from sIBL_GUI duties and spent some time continuing to work on Color, which is my soon to be open sourced Color Science Python Toolkit.

For now I'm just plotting the colorspaces in CIE Lab, but I'm planning to do also at the very least CIE xyY.
The good thing with plotting that in Maya is that you can do pretty renders of the colorspaces volumes.
Here is sRGB with ProPhoto RGB in wireframe:
And now ACES RGB, the colorspace to rule them all, the tiny solid guy in the center is sRGB:
