It doesn't sound like this is going to be decided by email votes, but just so the arguments for C don't dominate, my vote would be:
B > A >> C C has the least perceptual range (that's quantifiable, right?). Also, I find A and B much more aesthetically pleasing (that's obviously debatable). In particular, the yellows and blues in C have a slight visual vibration. Actually, if you google "visual vibration", one of the first hits is a yellow and violet image <https://web.njit.edu/~mmp57/visual%20vibration.jpg>. B would have this to a certain extent, but it's much more problematic if those colors are at the limits of the colormap range. It looks like A wouldn't have this problem at all since it's white point has a very muted yellow tone, so maybe I'll switch my vote to A. (Personally, it's a toss up between the two; anything but C, if I haven't made myself clear ;) Thanks to Nathaniel and Stéfan for putting this together! Hopefully "jet" can be banished soon :) -Tony On Wed, Jun 3, 2015 at 5:20 AM, OceanWolf <juichenieder-n...@yahoo.co.uk> wrote: > Personally, just looking at the images I think B looks more > professional, the others look faded.
