Some references to HTML regarding color

RGB means Red, Green, Blue. The minimum value of each primary color of RGB is 0 and the maximum value is 255. If converted into a hexadecimal representation, it is (#00) and (#FF). For example, white RGB (255,255,255) is represented by #FFFFFFF; and black RGB (0,0,0) is represented by #000000.
