HTML color codes are used to define colors in web design, usually in the form of a hexadecimal (HEX) code, RGB, or by name. Here’s a breakdown of the most common formats:

1. HEX Codes

  • A HEX color code starts with a # followed by six characters (numbers 0-9 and letters A-F), which represent the intensity of red, green, and blue.
  • Format: #RRGGBB
  • Example: #FF5733 (a shade of orange)
Color HEX Code
White #FFFFFF
Black #000000
Red #FF0000
Green #00FF00
Blue #0000FF
Yellow #FFFF00
Cyan #00FFFF
Magenta #FF00FF

2. RGB (Red, Green, Blue)

  • RGB colors define the intensity of red, green, and blue on a scale of 0-255.
  • Format: rgb(red, green, blue)
  • Example: rgb(255, 87, 51) (a shade of orange)

3. RGBA (Red, Green, Blue, Alpha)

  • Similar to RGB, but the fourth value (alpha) specifies the opacity of the color.
  • Format: rgba(red, green, blue, alpha)
  • Example: rgba(255, 87, 51, 0.5) (50% opacity of the same orange)

4. HTML Color Names

  • HTML also supports 140 named colors.
  • Example: red, blue, green, lightgray, darkslateblue
