I am new to darktable, as well as working with colors in general. Recently I was watching this great video made by @s7habo. It’s really helpful for me, and I appreciate the video.
At the beginning of his video, he talked about various ways to get orange and teal combinations via the channel mixer. The explanation in the video made sense, but I don’t think I fully understand the math.
For example, if I know that I want red to be converted to some hue, and blue to some other hue, how can I calculate the percentages I should apply in the channel mixer? In the video, we first start by mapping
Red to Orange
Magenta to White (I think)
Blue to Cyan
Cyan to Cyan
Green to Black
Yellow to Orange
The math in the video makes sense, but I’m not sure how to generalize it. How can I expand this to two (or more) arbitrary colors?
It seems like there must be a formula for calculating this stuff, but my internet search skills are failing me. I’d really appreciate any insights anyone can provide.
