Thank you.  To me, this is more comfortable to look at than A, B, and 
especially C.

Interesting.  That kink comes through as a visible over-emphasis of the 
orange range in the images.

Attached are two more variations on the clockwise dark-to-light theme. 
They achieve more dynamic range, and perhaps "colorfulness", but at the 
cost of more relative loss of contrast in the colorblind cases.  Is the 
tradeoff worthwhile?
