I'll just say that each color changes the shade if you put another color next to it. Our eyes try to see the difference in shades.



so to get its color, I just took a bright yellow, darkened it and removed the saturation. But since the next one is blue, he emphasizes the difference in color, making the gray tone of her fur coat seem yellow



but these are just words and blah blah blah.

there is a better way to learn how to work with color - if you draw a lot from life and nature. nature has long invented for us many beautiful combinations of colors and shades.
