Lets see, I'll dig out my source here.
In file stub.c, in the routine translate_color(), the
color numbers 0-15, 17-23 and 25 are hard-coded to non-dithered
colors. Colors 16 and 24 are of course "special" colors.
Colors 25-32 inclusive are as yet undefined. Colors 33 to
64 are intended to be transparent colors,
although only 33,34,36,39,41,42,46,47,and 57 are defined.
Anything greater than 256 is dithered, with the
highcolor = (c-256)/16 and the basecolor = c & 0xf.
Upon looking at the code, if you specify a transparent
color for the highcolor, you will get the highcolor mapped
to "empty", in effect making a transparent version of the basecolor.
In other words, color (33*16+256)+5 is a transparent version of
color 5. Not that I recommend that you do this, but that's
how it works.

| (...) What about colors 431, 495, and 382? They appear to be rendering as solid colors. (Note to self: colors 256, 273, 290, 307, 324, 341, 358, 375, 392, 409, 426, 443, 460, 477, 494, and 511 look solid because they are dithering a solid color with (...) (26 years ago, 28-Oct-98, to lugnet.cad)
