Colour notation refers to the methods used by colour models to identify and store colour values in a form recognisable to both computers and humans.
- The RGB colour model uses both decimal and hexadecimal triplets for colour notation. So RGB notation looks like this:
- R=255, G=128, B=0 is the decimal notation for orange.
- #FF8000 is the hexadecimal notation for orange.
- The HSB colour model uses decimal triplets for colour notation. So an HSB notation looks like this:
- H=30, S=100, B=100 is the notation for orange.
- The CMYK colour model uses decimal quadruplets for colour notation. So a CMYK notation looks like this:
- C=0, M=61, Y=100, K=0 is the notation for orange.
