![]() ![]() Eventually I gave up, sampled the desired color from a night sky photograph, and used the ArgyllCMS command line “xicclu” utility to systematically modify the LCH values, retrieve the equivalent RGB values, dial the RGB values into Krita’s advanced color selector, and then paint using the resulting colors. I was using Krita to paint colors into a black and white photograph, and I ended up spending a huge amount of time chasing that blue sky color around using Krita’s many HS"X" color modifying tools. For example, I coded up an LCH color picker for GIMP because I wanted to modify a blue sky color to make it darker and more saturated. My own interest in all this “mumbo jumbo” is grounded in finding practical answers to real digital darkroom problems. Which raises the very legitimate question of “Then what’s the point?” My answers, respectively, are “Maybe” and “No”. ![]() Those artifacts you often see when using the HSV blend modes? That’s because unlike LCH, HSV doesn’t cleanly separate color and tonality.Ī legitimate question (that I’ve been asked more than once) is “Does understanding all this color management/color science mumbo jumbo help me make better images?” Another question (that I’ve also been asked more than once) is “Do I need to know any of this stuff to make good paintings and photographs?” If anyone actually reads and follows along in the tutorial, I’d love to hear what you think about the LCH blend modes compared to the HSV blend modes. ![]()
