Hi Jester, Been looking for what your after and it's a pretty hard call. I don't have the exact colour in RGB because they varied so much in shade once in the field.
I've put a couple of links so you can see for yourself, you've probably see them already.
Jaguar Colours
Jaguar Colours II
This is quite a good photo in showing the contrasts in colour.
#1 Is a guesstimate
#2 Factory Finish
#3 British Army Desert Yellow
All 3 are over lade with #2 Desert Pink, So to get the colour that your after m8 I think is up to you. Sorry I can't help more.
