 a default color table and I'm adding my notes in the nested lists:

 Wow, you're really putting a lot of research into this. Thanks !

 I agree with all you are saying (I never defended rainbow as a good color
 table !), and if you all think that having a better (not good, as I don't
 think that exists, but better) default color table, then go for it. As
 said, if we change, then personally I would prefer grey (as this would
 force people to chose if they want color), but I hear what you are saying
 about the marketing aspect.

 One aspect your review doesn't seem to take into account is categorized
 maps. Many of the above arguments only relate to continuous, quantitative
 values, not qualitative data (and the landuse map in viridis is not very
 nice... ;-)), but I guess this is impossible to detect automatically, so
 different defaults for different types of maps does not make sense.

 So, for me, go ahead with whatever you feel is right...
