My suggestion for the file name is ldconfig.ldr.  This seems to identify the
file adequately.  I happened to have a fairly extensive colors file lying
around.  I cleaned it up, and here it is.  I'm planning to put in this file in
the 2003-02 parts update, in the ldraw/ directory.

Notice that this file won't actually work fully in any software, AFAIK.  The
main problem is that it attempts to define color codes in the 'dithered color'
range, which LDLite doesn't support.  But as I said previously, the content can
be hashed out over time.  The important thing is to get a file out there into
the hands of people who can dissect it. :)

Comments?  Suggestions?  Criticisms?

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 (...) (21 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 (...) (21 years ago, 29-Jul-03, to lugnet.cad, lugnet.cad.dev.org.ldraw)
