Detailed Description

Colour scale based on magma colour map.

This class linearly interpolates between values.

The colour map is "magma" created by Stefan van der Walt (@stefanv) and Nathaniel Smith (@njsmith). Full credit goes to them for their excellent colour scale. Details can be found here: https://cran.r-project.org/web/packages/viridis/vignettes/intro-to-viridis.html The values hard-coded in this class come from a json file on @stefanv, in the package "scale-color-perceptual", specifically https://github.com/stefanv/scale-color-perceptual/blob/master/rgb/magma.json

This file has 256 values and has been cut by a fraction of 1/8 to 32 values as we will linearly interpolate anyway and want to save memory.
