HTML color code has six values i.e #AADDBB. These six letters represent 2 for blue, 2 for red and 2 for green. The value begin from 00 (Minimium) to ff (Maximium) . If you want to create a color code, you must assume that what amount of color we need ? To create red color, we do not need green or blue, rather we need the maximum value of red color. So red = ff0000, similarly, Similar is the case make other color codes. If you understand the above fact, we can create any type color codes, by changing the parameres rather than learning those.
