[ENH]: callable color map of Plasma with Deuteranopia colourblind filter about matplotlib HOT 3 OPEN

It sounds like you might want to use the cividis map: https://github.com/benmaier/cividis.

in the caption we can point to the same colours as what the majority Color-blind would see

With any of the perceptually-uniform sequential colormaps in the viridis family, you should be able to use the universally-accessible terms "ligher" and "darker" to describe regions (or the polarity) of the colormap, and I'd suggest doing this over using hue terms like "blue" and "yellow". A problem with the colormap you're proposing here (and with cividis imo, but somewhat less so) is that it effectively turns the colormap into a bipolar scale that implies a categorical boundary somewhere around the midpoint, which may not be an accurate representation of the nature of your data. Unfortunately, color is super complicated.

Note that cividis is one of Matplotlib's built in color maps, so you do not need to install the linked package.
