Listing Color Maps

List all of the available color maps:

brewer2mpl.print_maps()

List maps by type:

brewer2mpl.print_maps('sequential')

Filter by number of colors defined:

brewer2mpl.print_maps('qualitative', 6)

Get a Color Map

Color maps are accessed by name, type, and number:

bmap = brewer2mpl.get_map('Paired', 'Qualitative', 5)

If you want a color map reversed from how it is given by colorbrewer2.org set the reverse keyword to True:

bmap = brewer2mpl.get_map('Paired', 'Qualitative', 5, reverse=True)

BrewerMap Objects

Color maps are represented by BrewerMap objects. They have a few useful attributes:

# colorbrewer2.org url.
# Copy this into your browser to see the map at colorbrewer2.org.
bmap.colorbrewer2_url

# colorbrewer2.org name
bmap.name

# number of defined colors
bmap.number

# colors as a list of RGB 0-255 triplets
bmap.colors

# colors as a list of hex strings
bmap.hex_colors

# colors as a list of RGB 0-1 triplets (as used by matplotlib)
bmap.mpl_colors

# matplotlib color map
bmap.mpl_colormap

The matplotlib color maps are created using matplotlib.colors.LinearSegmentedColormap.from_list. If you want to pass options to that method use the BrewerMap.get_mpl_colormap method:

cmap = bmap.get_mpl_colormap(N=1000, gamma=2.0)
