Effect
Color Matrix
Transform colour with a full matrix for precise channel cross-talk.
A colour matrix is a linear transform across RGB: each output channel is a weighted mix of the inputs. Broadcast engineers and colour scientists use matrices for space conversions; artists use them for cross-talk looks that a simple balance slider cannot reach.
It is precise and a little abstract. Small off-diagonal values create channel bleed that feels optical rather than painted.
