Bottom/dye colors of DVDR's

[deadlettr]

Yes, this is probably a bit of a strange question....
When recordable CD's first came out, the bottom of them (the dye/burnable side) was usually blue or green (or tints of those so I'm generalizing here) but then it seemed like CDR bottoms/dyes were every color of the rainbow (including black)-and I suppose still are.
So far about the only bottom dye colors I've seen for DVD-R's are purple or blue. Are there any others colors out there? I'm actually looking for silver/silver (top/bottom) as they looked more "realistic" when burning the CDR's and it'd be cool to duplicate the same look on DVDs....however, if it turns out there there are ones out there but they're cr*p, then obviously I'll take quality first.
Anyways, just one of those gee wiz questions I got thinking about and I haven't come across any info on the net and the few stores I've checked with on-line (CDW, TigerDirect, etc) have no clue.
Thanks for helping me out with this trivia.

You will only see silver in commercial pressed discs. The purple or similar color is the color of the dye needed for burning DVDs.

All CD dyes are basically blue, silver-blue, green or silver-green. Those are the colors of the metal azo, cyanine and cyanine-based dyes.

All other colors are really the color of the plastic on bottom (or the plastic color merged with disc color). Some may even have pigments adds, but not often because it can harm CD quality.

DVD media is all shades of purple. Again, because of the materials used. Some tint pink, some tint blue, some tint brown ... but they are all esentially purple (or violet or whatever).

Again, color of dye.

Silver "bought" discs are pressed metal, gold or silver (color, not metal), usually silver. The actual materials are aluminum or whatnot.
