Testing also 3.7 beta 39, windows, with 3 colours/textures (0, 0.5, 1:
white, black, green; in that order, with ambient 1 diffuse 0 reflection
0 and no light source)

Confirmed for:
==============
bozo
bumps
dents
granite
spotted

doubtful (but very possible, at least different):
=========
wrinkles

The color_map is darker, more greyish, less saturated (no pure white, no
pure green: no extreme 0 or 1)

if the colour are black, white, green (in that order), the color map is
more white

Replacing color_map with pigment_map has no effect.

Seems fine:
===========
agate
boxed
cells
crackle
cylindrical
gradient
leopard
marble
onion
planar
quilted
radial
ripples
spherical
spiral1
spiral2
waves
wood
