No more rainbow colormaps

ImageAs kind of a short follow up to my previous post IBM on colormaps, I want to point out a blog entry on visual.ly, that convincingly describes some of the disadvantages of rainbow colormaps. The main points listed are:

  1. Colorblind people cannot use them.
  2. The divisions between hues create edges in the visualization.
  3. The spectral order of hues has no inherent meaning.
  4. Yellow is special.
  5. Detail is actually harder to see in a rainbow.
