# Colourettu version 2.0 documentation¶

Colourettu is a small collection of colour functions in Python. These can be used to determine the (relative) luminosity of a colour and the contrast between two colours. There is also the palette class for dealing with a ‘list’ of colours.

To install colourettu, the easiest way is to use pip:

pip install colourettu

## Note on Spelling¶

I have used the Canadian/British spelling of colour through this and the code.
