This repository is deprecated and not being updated anymore.

The code was integrated into the qim3d library, with some extra features: https://platform.qim.dk/qim3d/viz/#qim3d.viz.colormaps.objects

You can install with pip install qim3d

And easily create a colormap:

import qim3d
cmap = qim3d.viz.colormaps.objects(nlabels=100, style='bright', first_color_background=True, background_color="black")

rand_cmap

Creates a custom random colormap to be used together with matplotlib, useful for segmentation tasks. You may choose the first or last colors to be black. Also, two types of colormap can be generated, 'bright' and 'soft'. On both cases, the generated colors are restricted to never be too bright or too dark.

Examples:

Bright colors

Generating a colormap for 100 labels, with first as black

new_cmap = rand_cmap(100, type='bright', first_color_black=True, last_color_black=False, verbose=True)

Soft colors

Generating a colormap for 50 labels, with last as black

new_cmap = rand_cmap(50, type='soft', first_color_black=False, last_color_black=True, verbose=True)
