I've updated this @BetterFigures post on "picking a colour scale for scientific graphics" to include a colourblind-friendly categorical palette, and to reference viridis directly. betterfigures.org/2015/06/23…#endrainbow
We tested Rainbow against Viridis colour palettes for finding a subtle feature in data. You probably will believe what happened: wp.me/p2JKQZ-8z#endrainbow
Can you find the discontinuity? dougmcneall.shinyapps.io/dis…
This test app asks you to find the discontinuity in either Rainbow or Viridis colour palettes, and saves your answers. A bit of #endrainbow fun, idea by my friend Tim Graham
So we need a standard that allows a presentation to be trivially broadcast to a room, and received by an app that can then recolour plots as desired by the user. Could also swap fonts, zoom, etc. Plugin for Powerpoint, etc. Feasible.
