When dealing with very small icons being shrunk via transformed it appears the color var gets lost due to anti aliasing?
I should point out the top example is a 2x2 pixel image spammed (akin to ms paint) I did this to make it easier to see. The bottom is a 1x1, the smaller scale version is shrinking the "brush" to half.
Numbered Steps to Reproduce Problem:
Take a 1x1 pixel and multiply it's transform var by 0.5 while it has a color applied to it. Even it's overlays colors are also lost; instead of becoming white the pre-color color it becomes black, so I assume this is related to but not exactly: http://www.byond.com/ forum/?post=1376121&hl=color#comment6560211
