RGB Color Standard
When it comes to picking out colors to use on a client device such as a computer, mobile device, or tablet, the programmger has a wide range of colors to choose from. They can decide whether to use Hexidecimal style, HTML style or CSS to specify colors. CSS uses actual color names while HTML uses three sets of numbers to define the RGB scale. Here, we will discuss the hexidecimal way of specification.
The first to know about Hexidecimal classification is the range and meaning of every symbol in this 6 character string. Hexadecimal has a base of 16, which means the scale runs from 0 to F. The scale begins at 0, which is the lowest of that scale and runs all the way up to F, the max. Now the reason we don't use numbers is because the colors red, green, and blue and represented by two values. Three colors with two colors amounts to six characters/values. This is one of the reasons why there are no numbers above the value of 9.
To help convey the meaning of Hex numbers, here is the color white in hex:
#FFFFFF
and here is the color black:#000000.
If this is the first time you're seeing something like this it might seem strange, but allow me to explain. The first two numbers in that string represent the Red scale, the following two represent the Green scale, and the last two are for blue. Therefore, if we wanted to say the first character, the first value of red is worth ten, we have to say #A00000. If we tried using ten in the first spot, we wouldn't have a six character string anymore, or it would look like this: #100000 which is a totally different color than the one we want. You can go on google and type in a similar hex number as to those above to see what color you get. The background color of this page is #C6E2FF, and if you google that, you'll get the color you see here!
