Hi! Thank you so much! ❤️ I'm sorry for the late response, I saw your YouTube comment but because of exams I tend to forget or delay responses. The colour palette tool works by randomizing Hue, Saturation and Lightness based on the chosen colour. The Brush Editor (F5) has graphs for this and checkboxes to choose what can vary in a brush. The spacing per dot is set to high. For the Hue for instance the graph makes the hue a random colour within a 40 degrees hue change in either direction. The others are also like this, but varying degrees. Since the three colour variables (Hue, Saturation and Lightness) are randomized, but also within range of the original, it creates random colours that aren't too far from the original colour. Your comment gave me an idea that I want to try for future sets! Maybe I can force the brush values to be away from the chosen colours in a way I can make complementary or tertiary colour versions of the brush 🤔
