Why use colour models

About why we use colour models

• Colour models help to relate and coordinated colours with one another when working with different light sources, media such as paints or inks, objects and materials.
• Colour models clarify the ways in which coloured lights, transparent inks and opaque paints (etc.) all produce different results when mixed.
• Colours models help us manage the fact that colours behave and appear differently:
  • When emitted by different types of light sources.
  • Depending upon the type of media – inks, dyes, pigments.
  • When seen or used in different situations (indoors, in sunlight, in low light, on a digital display etc.)
  • When applied to, mixed with, or projected onto different materials.
  • When used for different purposes (fabrics, electrical wiring and components, print media, movies etc.)
