What is it ?

colormap package provides simple utilities to convert colors between RGB, HEX, HLS, HUV and a class to easily build colormaps for matplotlib. All matplotlib colormaps and some R colormaps are available altogether. The plot_colormap method (see below) is handy to quickly pick up a colormaps and the test_colormap is useful to see test a new colormap.

Installation

pip install colormap

Example

  • Create your own colormap from red to green colors with intermediate color as whitish (diverging map from red to green):

    c = Colormap()
mycmap = c.cmap( {'red':[1,1,0], 'green':[0,1,.39], 'blue':[0,1,0]})
cmap = c.test_colormap(mycmap)

  • Even simpler if the colormap is linear:

    c = Colormap()
mycmap = c.cmap_linear('red', 'white', 'green(w3c)')
cmap = c.test_colormap(mycmap)

  • check out the available colormaps:

    c = Colormap()
c.plot_colormap('diverging')
