Since no software can handle the file right now, I suggest the format is changed into:
0 COLORDEF color name edgecolor r g b dr dg db material

COLORDEF in stead of COLOR to avoid confusion with ldlite COLOR.

For edgecolor you can also use extended colors 0x02RRGGBB,
which is supported by MLCad/LDView/L3P/L3Lab,
see http://www.hassings.dk/l3/l3p.html#extcol

"a" is left out (since it is always 255 ?)

"da" is left out, use material=transparent.

You can specify "dr dg db" as "-1 -1 -1", which means no dithering.
It is easier than replicating the "r g b" values, and is less error prone.

"material" added, can be normal/transparent/rubber/metallic/glowing
The rubber is a convenient shortcut, as a "0 MATERIAL RUBBER"
in the tire files would be preferred.
Then you could easily have a (virtual) green rubber tire.

Example:
0 //      Code ColorName        EdgeColor    R   G   B    DR  DG  DB Material
0 COLORDEF   0 Black                    8   33  33  33    -1  -1  -1 normal
0 COLORDEF   1 Blue                     0    0  51 178    -1  -1  -1 normal
0 COLORDEF  21 GlowDark         0x277cc00  224 255 176    -1  -1  -1 glowing
0 COLORDEF  25 Orange           0x2000000  249  96   0    -1  -1  -1 normal
0 COLORDEF  33 TransBlue        0x2002266    0  32 160    -1  -1  -1 transparent
0 COLORDEF 256 RubberBlack      0x2000000   33  33  33    -1  -1  -1 rubber
0 COLORDEF 334 ChromeGold              15  196   0  38   255 220   0 metallic
0 COLORDEF 375 RubberGray               8  193 194 193    -1  -1  -1 rubber
0 COLORDEF 383 ChromeSilver             8  255 255 255   193 194 193 metallic

(...) Right off the bat, I'd like to say that I think using a different notation for (A)RGB would be a good thing. Whether it's #RRGGBB or something else, I don't care. Also, should we go to a tagged format? Tags could make it easier to support (...) (23 years ago, 16-Aug-03, to lugnet.cad.dev.org.ldraw)

[XPFUT lugnet.cad.dev.org.ldraw] (...) A little more has happened on this: I emailed the authors of most of the LDraw-compatible software packages, and asked for buy-in on this idea. Basically, my thought was that we needed to have agreement about (...) (23 years ago, 29-Jul-03, to lugnet.cad, lugnet.cad.dev.org.ldraw)
