Vary background color

[leapingllamas]

@fchollet An intelligent agent should be able to recognize focal objects versus background, even if background color might vary among training examples.

There are various examples of deep-learned systems that recognize B&W digits well but fail spectacularly when colors are simply inverted. I would like to see an intelligent ARC-solver that is robust to this.

All the ARC examples I have seen so far have black backgrounds. Thus, I propose that ARC is augmented with examples with different background colors, sometimes yellow, sometimes white etc.

No! Don't make it even harder...!

Although there are some tasks included already that require you to detect shapes in colored 'noise'; e.g. 1c786137.
