The LDraw colors are 0-15, 32-47, 256-511 (and of course 16 and 24).
Paul Gyugyi defined some more colors for LDLite, 17-23, 25, 57
and "Direct Colors" in the range 0x04000000-0x07FFFFFF.
As MLCad supports these colors, I'm going to add support for them too.
However, Gyugyi packed two RGB's (for dithering) into each Direct Color
leaving only 12 bits to each RGB, e.g. 0x04RGBRGB.
Some L3P and L3Lab users have asked for the possibility to specify
"true colors" (24 bit RGB's), so I would like to define/reserve the range
0x02000000-0x03FFFFFF for this.
0x02RRGGBB for solid colors and 0x03RRGGBB for transparent.
I will support, but not require, hex notation for colors (0x/0X prefix).
I hope MLCad, LDLite and other tools will support the new range too.

| (...) I will have to find a way how to define such colors in MLCad but I think I will provide an option where the user can define if he/she likes 24bit or 12bit colors. Generally no problem :-) Michael (25 years ago, 2-Mar-00, to lugnet.cad.dev)

During implementation of Gyugyi's Direct Colors, I browsed his LDLite code: | if ((c >= 0x4000000) && (c <= 0x7ffffff)) | { | /Numbers of 0x4000000 to 0x7ffffff are hard coded color values. | zcp->r = 16 * ((c & 0x00000f00) >> 8); | zcp->g = (...)
