CSS Short Hex Code:

• Short Hex Code is a shorter form of the six-digit notation. In this format, each digit is replicated to arrive at an equivalent six-digit value; For example: #F00 becomes #FF0000.

• Nearly all browsers (version 3 and above, except IE3 Mac) support shorthand hex colors.

• Each hexadecimal code will be preceded by a pound or hash sign #. RGB triplets can be abbreviated if each of the Red, Green, and Blue hex pairs are the same. So when you use colors where there are three pairs, you can abbreviate each color channel using one character instead of two identical characters.

• Browsers automatically expand these three-character colors into six by replicating the R, G, and B values. This technique saves a few bytes for each color abbreviated with shorthand hex notation.

CSS RGB Values:

• This color value is specified using the rgb( ) property. This property takes three values, one each for red, green, and blue. The value can be an integer between 0 and 255.

NOTE: All the browsers does not support rgb() property of color so it is recommended not to use it.
