HEX COLOR CODES
The most popular are Hex color codes; three byte hexadecimal numbers (meaning they consist of six digits), with each byte, or pair of characters in the Hex code, representing the intensity of red, green and blue in the color respectively.
#XXXXXX
Hex code byte values range from 00, which is the lowest intensity of a color, to FF which represents the highest intensity. The color white, for example, is made by mixing each of the three primary colors at their full intensity, resulting in the Hex color code of #FFFFFF.
#FFFFFF
Black, the absence of any color on a screen display, is the complete opposite, with each color displayed at their lowest possible intensity and a Hex color code of #000000.
#000000
Understanding the basics of Hex color code notation we can create grayscale colors very easily, since they consist of equal intensities of each color:
#454545
#999999
The three primary colors, red, green and blue, are made by mixing the highest intensity of the desired color with the lowest intensities of the other two:
#FF0000
#00FF00
#0000FF
