Good concept for high-contrast and print material. I downloaded this with intent to use it for printable material, but it fails on a few important fronts:
Color of interactive Python console text is the same as the background of the console, making it invisible.
The xyz axes in the 3D Viewport are all the same color, where they are usually green, red, and blue, making them indistinguishable when switching between global, local, and normal transformations.
Not bad!
