"sunset" has a connotation of things ending. Howabout "sunrise"?

How would you go about doing this in practice? Is it even possible to
choose a subset of sRGB space and have printers take advantage of that when
doing gamut mapping? (I guess I always assumed that printer gamut mapping
applied to an RGB image would map all of RGB into their gamut, so there
would be no advantage to restricting oneself go a subspace. But maybe I'm
wrong -- color management is pretty fancy these days.)

Just wondering whether anyone has suggested checking candidate colormaps
against typical printer color gamuts?

I checked with my red-green color-blind colleague, Niklas Schneider, and 
his evaluation is attached.

Eric

I like it, but perhaps we should condense it to one word for ease of 
typing, how about "Redgauntlet"?  It kind of feels appropriate (for 
those who need an explanation of why, see 
https://www.youtube.com/watch?v=_guKhYVr5vA).

On the colormap itself, it looks good apart from the fade into blue, my 
eyes on this laptop monitor see a sharp gradient around 0.2 compared 
with the more gradual gradient at the other end.  Also I see constant 
colour between 0 and 0.1, and between 0.9 and 1, with less change 
between 0.8 to 0.9 then 0.1 and 0.2.  Not sure if one causes an optical 
illusion in the other or not.

Finally a bit confused as to what all the lines mean, any chance of some 
annotation?  Also I would find it helpful to see a version without the 
big red line and what it looks like in practice (see the doc for the 
test script).

Best,
OceanWolf
