"The derive function takes a color and computes a brighter or darker version of that color. The second parameter is the brightness offset, representing how much brighter or darker the derived color should be. Positive percentages indicate brighter colors and negative percentages indicate darker colors. A value of -100% means completely black, 0% means no change in brightness, and 100% means completely white."
