I have never seen a T1N in dark green.
Dark Green was a standard (i.e. didn't cost extra) color for the T1N during the 2002 through 2006 model years (and probably still is).
(we would've bought it if one had been available on the lot that day... )
When i can find the paint codes/names for those years, i'll edit them into this reply
(i could type them in from a 2005 sales brochure, but that would be exceedingly boring...)
Oh, what the hey:
Flame Red, Arctic White, Brilliant Blue, Black Gray, Calcite Yellow, Graphite Metallic,
Silver Gray, Steel Blue, Black Blue, Amber Red Metallic, Jasper Blue Metallic, Brilliant Silver Metallic,
Black, Stone Gray, Orchid Green, Hyacinth Blue, Carbon Black Metallic, Piedmont Red
Anything with the word "metallic" as $895 extra.
The picture in the brochure shows "Orchid Green" as being far brighter than it looks in the flesh.
