Color - Space (Model)


A color space determines how a tuple of data values (e.g., an RGB triplet) maps to a well-defined color (and vice-versa).

A color space is a specific organization of colors where you can:

  • define
  • and compare them.

Each color spaces use a different set of parameters to describe the colors.

Many color spaces can be represented as three-dimensional values (three parameters) but some have more, or fewer dimensions, and some, such as Pantone, cannot be represented in this way at all.

When defining a color space, the usual reference standard is the CIELAB or CIEXYZ color spaces, which were specifically designed to encompass all colors the average human can see.


  • a greyscale color space only has one parameter which controls the level of brightness going from black to white.
  • RGB color space use red, green, and blue as parameters representing the colors of the lights in a display that add together to make a final color.
  • CYMK color space with Cyan, Yellow, Magenta and black are the parameters representing the colors of the inks.
