I am seeing broken colors on an MT8173 Chromebook with next-20240912,
which goes away if I git-revert this series (commits 1f66fe62cc09
eb17c5909481 a3f7f7ef4bfe 59e9d9de25f0 4225d5d5e779).

To illustrate, I took a picture [1] of some color mixing diagrams from
Wikipedia [2]. Do you have an idea of what goes wrong?

(I'm busy with too many things so I don't want to debug it now...)
