Abstract

Existing colour spaces contain huge amount of colours describing their spaces. However, graphic devices are able to reconstruct only limited number of colours. This set of available reconstructed colours, called a colour palette, must be selected from a wide variety of possible colours in particular colour space. Device dependent colour spaces (for example RGB gamut) often uses many different palettes depend on specific needs. There are known many colour space quantization algotihms elaborated to that colour spaces, but we do not find palette for our needs. We try to find a palette for colour object identification tasks, so we consider L * a * b * colour space and ΔE difference.
