Thanks Ted, I'll take a look at it and give it a try.

I mentioned about keeping white balance constant while messing with the sliders. After some research in the world of matrices, a popular theme is that each row should sum to one, although it wasn't obvious why.

Anyhow, I tried keeping the sum for each output channel to 100% in the RT mixer:

The WB picker gave me about the same numbers for the sky for both left and right

However, selecting slider values seems not be highly intuitive. In the right pane, I tried to reduce the very slight red appearance of the sky by setting the blue channel sliders to -20%R, 0%G, and +120%B. Did not get what I expected ...
