The problem was to find a good colour scheme for heatmaps (but also for plots of points in treespace). In the end I settled on grayscale, because all the others give frustrating artefacts, and look awful if you print them. \r\n\r\nThis talk presents a new colormap called viridis from matplotlib, which Vince Buffalo pointed out is already in an R package by the same name:\r\n\r\nhttps://twitter.com/vsbuffalo/status/631594457901568000\r\n\r\nSo, let's use it. The colormap is pretty, it works for colorblind folks, and it translates to grayscale for printing. "}}
