biopython v1.71.0 Bio.Graphics.ColorSpiral
Generate RGB colours suitable for distinguishing categorical data.
This module provides a class that implements a spiral ‘path’ through HSV colour space, permitting the selection of a number of points along that path, and returning the output in RGB colour space, suitable for use with ReportLab and other graphics packages.
This approach to colour choice was inspired by Bang Wong’s Points of View article: Color Coding, in Nature Methods 7 573 (doi:10.1038/nmeth0810-573).
The module also provides helper functions that return a list for colours, or a dictionary of colours (if passed an iterable containing the names of categories to be coloured).
