RGB (Red, Green, Blue)

RGB color values we can use: rgb(red, green, blue)

In the html red, green, and blue defines the intensity of the color between 0 and 255.

For example, rgb(255,0,0) is displayed as red, because red is set to its highest value (255) and the others are set to 0. Experiment by mixing the RGB values below:

Red Green Blue
255 0 0

Example

Color RGB
  rgb(255,0,0)
  rgb(255,255,0)
  rgb(0,255,0)
  rgb(0,255,255)
  rgb(0,0,255)

Shades of gray are often defined using equal values for all the 3 light sources:

Example

Color RGB
  rgb(0,0,0)
  rgb(128,128,128)
  rgb(255,255,255)

Hexadecimal Colors

With HTML, RGB values can also be specified using hexadecimal color values in the form: #RRGGBB, where RR (red), GG (green) and BB (blue) are hexadecimal values between 00 and FF (same as decimal 0-255).

For example, #FF0000 is displayed as red, because red is set to its highest value (FF) and the others are set to the lowest value (00).

Example

Color HEX
  #FF0000
  #FFFF00
  #00FF00
  #00FFFF
  #0000FF
