***IMPORTANT*** Colors given in the five variables are not the same as each other. Hex is the six-digit color setting thing that is used in most custom color setters. RGB is the addition primaries. HSV/HSB is, in my opinion, the easiest way to set color, which is hue, saturation (how not-gray the color is), and value/brightness (how much color there is) HSL is similar to HSV, except with lightness instead of value. lightness takes it from black, through the color determined by the hue and saturation (color and non-grayness), to white. CMYK is the subtraction primaries, and black. for HSL and HSV, the hue can be anywhere from 0-360, but Scratch uses 0-100, so you might have to go to desmos.com/graphing to convert it, just use (Hue)/3.6 to go from 360-100, and 3.6*(Hue) to go from 100-360.
