Many images show the tartan being far too bright, the one below is another good representation I feel:
This example shows the pattern clearly, although it does appear far too bright to my eyes.

Key is I think to keep the overall look quite dark for this regiment.
OK, so it took a fair bit of trial and error to get to something that begins to look like the Government Tartan! First attempt was a disaster and a waste of an hour or so, but it's a learning process, I repainted the base coat dark green and on the second attempt painted broad (Dark Prussian Blue) checks before slightly highlighting the green with Luftwaffe green to try to build up the pattern. I then applied thin black lines in a check pattern, but the result was the black was lost against the Prussian Blue over the basecoat, I re applied the back check pattern but same result, I think the black was a little thinned down to keep the flow steady. Unsure of how to improve it I then decided to bring the blue checks up a little with Vallejo Intense Blue. Looking at the overall effect from a foot or so away at this stage I'm fairly happy and now that I have a method the next lot will be far easier. The main thing is the contrast with the 92nd regiment looks about right to me.
Still fair way to go yet, muskets, socks, gaiters, faces, bonnets to finish off, challenging but rewarding are the Highlanders!
Edit: Following the comments below I decided to try a thin black wash to knock the brightness of the pattern back a little more. I think it's an improvement (below) BUT...... Robs description of the pattern as more diagonal has helped a lot, I have trouble seeing tartan patterns for some reason, they just don't seem to register with me, so might be worth another shot to see if I can get closer.
