Requirements

The module has been tested to work with:

python = 3.9.12
matplotlib = 3.5.1
numpy = 1.21.1
scipy = 1.7.1 (only needed for colourmaps)

Functionality

The module has three methods:

• safeColours.distinct_named() provides a dictionary of up to 13 different colours, all with unique names. The available colour names are: navy, cyan, turquoise, green, olive, sandstone, coral, maroon, magenta, brown, skyblue, pink, blue

• safeColour.distinct_list(n_colours) provides a list of length n_colours where the choices of colours maximise the contrast.

• safeColour.colourmap(maptype, invert=False) provides a choice of three colour maps. The maptype choices are: diverging, heat, rainbow. Setting invert=True reverses the colour sequence.
