#three {  background-color: rgb(255, 0, 0);  }
#four  {  background-color: rgba(255, 0, 0, 1.0);  }
#five  {  background-color: hsl(0%, 100%, 0%); }

Predefined Color Codes

Hexadecimal Color codes

The hexadecimal RGB shading documentation is the most seasoned shading documentation (together with predefined shading codes). The hexadecimal RGB shading documentation parts any given shading subtlety into three segments: Red, Green and Blue. That is the place the three letters RGB originate from. Any shading is made out of a specific measure of red, greeen and blue shading.

Example -

#ffffff;

RGB Colors

RGB color format is similar to hexadecimal color format. Each color is specified as a mixture between red, green and blue colors. Instead of using hexadecimal numbers, you use the decimal number betwen 0 and 255. Here is an example RGB color:

Example -

rgb(255, 0, 255);

RGBA Colors

RGBA hues mean Red, Green, Blue and Alpha. The RGB part is the same as in RGB hues. The An (alpha channel) determines the mistiness of the shading. The alpha channel esteem can be set between 0 (completely straightforward) and 1.0 (completely hazy). Here is a RGBA shading case:

Example -

RGBA (255, 0, 255, 1.0);

HSL Colors

HSL hues (Hue, Saturation, Lightness) are new in CSS 3.0. In the event that you are an architect you may be more used to working with HSL hues than RGB hues. You can indicate HSL hues this way:

Example -

hsl(0%, 100%, 0%);
