Quoting from this thread ( Elle's Writing and Articles)
I did incorporate @afre’s suggestions into the second of the two LCH tutorials I’m working on, and I think this tutorial is mostly finished, pending questions, suggestions, errors spotted, etc:
This is the table of contents and some images, on the assumption that images speak louder than words:
A. Introduction: Choosing complementary colors, color harmonies, and colors for painting warmer highlights and cooler shadows: Why LCH is so much better than HSV
B. LCH (approximate) hues for highlights and shadows
C. Painting highlights and shadows on a sphere using an off-complementary color harmony
D. Coloring a black and white photograph to emulate early morning lighting and some notes on the trouble with yellow and blue
E. A triadic color harmony
F. Conclusion: Who needs LCH? and notes, and how to use GIMP’s LCH color sliders to pick the brightest, highest chroma color for a given LCH hue
I’m pretty sure that no one will ever learn very much about LCH or other topics covered in tutorials on my website, just by reading the tutorials. My tutorials are about the practical and applied aspects of color management, color mixing and such. These are things that imho don’t start to make any sense until you are actively experimenting and incorporating your observations into your workflow. The tutorials are intended merely as guides to starting the process of experimenting.
I’ve learned a lot from writing tutorials, from the process of creating images and learning new stuff in an attempt to explain something that often turns out to not be as obvious as I thought it was. I think sharing explorations is whole the point of the pixls.us forums, and I’ve learned a lot following the threads on this forum. We learn from each other. My LCH tutorials are an attempt to share what I’ve learned, and I’m looking forward to seeing and learning from what other GIMP users and pixls.us forum members will do with the new LCH color tools.
