I am afraid I can't help much, Bill. My notes on the Border Regt relatied mainly to the 34th, but as the colour featured in regimental items across the board- stable belts, ties etc, it ought not be too hard to find examples.
The regimental museum at the former Border Regiment HQ in Carlisle Castle should be able to point you in the right direction:

Stop press. This might be a guide:

I hope that helps.
