chroma – Chroma: a reference book of colours

This reference book presents several lists of colours and their respective parameters in a number of colour models. The lists are constructed either by parameters or by name.

‘Colours by parameters’ displays systematic series of colours, based on 3-tuples of numbers that are interpreted as colour parameters in the ‘rgb’, ‘cmy’, and ‘hsb’ colour models.

‘Colours by name’ displays sets of colours that have been given specific names such that users do not have to care about their parametrisation. However, as soon as there is the intention to use these colours outside the world (e.g., website construction or drawing programs), the parameters suddenly gain importance. For each colour name, we display:

  • the colour itself plus the name of the underlying model,
  • a 50%-tint (mixture with ‘white’),
  • a 50%-tone (mixture with ‘gray’),
  • a 50%-shade (mixture with ‘black’), and
  • the complementary colour.

Additionally, for the base colours defined by the xcolor package, also all 50%-mixes of base colour pairs are included.
