So you are pondering "Does this odd blend of letters and numbers have any importance?" Well the appropriate response is "Yes" and this is the manner by which it goes:)
HTML Codes group:
Every HTML code contains image "#" and 6 letters or numbers. These numbers are in hexadecimal numeral framework. For instance "FF" in hexadecimal speaks to number 255 in Decimal.
Which means of images:
The initial two images in HTML color code speaks to the force of red color. 00 is the least and FF is the most extreme. The third and fourth speaks to force of green and fifth and 6th speaks to the power of blue. So with joining the power of red, green and blue we can blend practically any color that our heart want;)
