To clarify: I did "git checkout eccea7920cfb009c2fa40e9ecdce8c36f61cab66", tested the kernel and got that colors problems. On top of that commit I simply did "git revert eccea7920cfb009c2fa40e9ecdce8c36f61cab66", re-tested, and colors were OK again. So it's definitely matter of eccea7920cfb009c2fa40e9ecdce8c36f61cab66.
