HEX, RGB and HSL: which one to use
HEX (#6F5FE6, for example) is the format Canva, Figma, Word and almost every design program ask for. RGB tells you how much red, green and blue the color has, from 0 to 255, and is common in PowerPoint and in code. HSL describes the hue, saturation and lightness, and is handy for creating lighter or darker variants of the same color.
