RGB colour values

RGB colour values refer to the numeric codes used in RGB colour notation to define specific colours in a digital image or on a digital display.

  • Colour values are numbers and characters used by colour models to represent and store colour information in a format recognizable to both computers and humans.
  • Each colour within a colour model is assigned a unique colour value.
  • The notation for RGB colour values (codes) are decimal triplets (base 10) or hexadecimal triplets (base 16).
  • RGB decimal and hexadecimal triplets look like this:
    • R = 255, G = 128, B = 0 (255,128,00) is the decimal notation for orange.
    • #FF8000 is the hexadecimal notation for orange.
