I had a BRG or rather TRG (I think the official name of the color was Triumph Racing Green) TR4A, anyway it is a really nice color and a 4A looks great in it, looks good with the black interior and wood dash. It is also a nice medium dark green, some of the other BL greens are either a little too dark or rather light, all a matter of taste, but all BRGs are not created equal, so do your homework when you pick the color.
Unfortunately the car was owned before digital cameras were as common as cocroaches so if I wanted to post I pic of it I would have to find the pics, scan the pics, upload the pics, post the pics, although it wouldn't take appreciably longer than it took me to type all this I would have to get up a move around and look for things and remember how to do things like scan pictures that I haven't done for a while, so too lazy to be that much help.
I bet if you google a TR4A you could find a few pics though.
