1.2.4. Unit-Summary

The following list recapitulates the main aspects of this unit:

• On screens, colours are represented in the RGB (Red, Green, Blue) Colour Model. The RGB colour model is an additive colour schema. Therefore the primary colours sum up to white.
• The colour depth defines how many colours are used in a picture. The basic information unit is a bit, which represents two states.
• To visualise colours on a screen they have to be coded. We have two possibilities to do the encoding: either with numbers or in hexadecimal codes.
