Two-dimensional data is often represented using “heatmaps”. Your choice of colormap is a crucial part of how your data is perceived. WrightTools has a few choice colormaps built-in.
All of these are held in the colormaps dictionary.

Throughout WrightTools you can refer to colormaps by their name. By default, WrightTools will use the default (signed) colormap when plotting un(signed) channels.
There are many great resources on how to choose the best colormap. Choosing Colormaps is a great place to start reading. WrightTools tries to use perceptual colormaps wherever possible. When a large dynamic range is needed, the data can always be scaled to accommodate.
The default colormap is based on the wonderful cubehelix color scheme.  The cubehelix parameters have been fine-tuned to roughly mimic the colors of the historically popular “jet” colormap.
The isoluminant series are instances of the color scheme proposed by Kindlmann et al. 
The skyebar series were designed by Schuyler (Skye) Kain for use in his instrumental software package COLORS.
