"JER, please explain your poem entries for level 1260. Do you like RBR?"

My text entries rarely carry any conscious message about anything related to the grid. I like RBR too, I wish his sticks and stones would have spread over the whole level.

"The dark TV in b3 is supposed to balance the dark part of c1 (and a2) and to a lesser extent b2."

I don't know. Those color blends may be too subtle for me. All I see is the harsh contrast of your square c2 which makes it stick out. The light grey I used at the bottom of C1 would have been so easy to use and blend with- your square simply looks like it's ignoring the rest of the level,

"The biggest risk that I took is so many rectangles."

Well, yes in a way. I don't have any problems with rectangles per se, but I don't see that level being about rectangles. Looking at your three squares it's pretty obvious you got your own thing going on, exorcising your personal demons as it were. Nothing wrong with that, but it doesn't feel like collaboration to me.
