I am learning how to icon. Can someone tell me when you use a different brightness(lum) of the same color in an icon? I know one reason is because of the lighting. Another reason is an outline. But those aren't the only reasons why I see different brightness of the same color. There are squares inside of an outline (for example: arms, legs etc...) that is the same color but have different brightness. I attached an example. See there are different brightnesses of the same color within the arms, legs etc... How and especially when do you change the color's brightness within the icon?
