From your post Duffy it seems that you are asking about matching a solid color fabric to a color in a Tartan. Is this right?
If so the "Same batch" rule would not apply. That rule is only for matching Tartan to Tartan. It would also be very unusual to find a Tartan weaver who offers solid fabrics to match. One weaver does give listings of coordinating solid colored fabrics to line a jacket with, but they are the only one I know that does as they produce Tartans, Tweeds and solids. But this is not the usual.
My advice would be don't worry about matching solid colored fabrics exactly to one color of a Tartan. The only thing I would NOT do is pick solid colors that clash with your Tartan. Solid Orange with a Predominantly Blue Tartan may not go too well.
I would also avoid clashing patterns too much. A small pattern or subdued pattern in a vest is nice. A vest in a large or loud pattern like another plaid - well, maybe not.
The idea is to coordinate, not to match. I use - as a rule of thumb - Blues blacks and greys together while reds, yellows and browns together. But this is not hard and fast. Brown tree bark and Green leaves go real well against a Blue sky. Can't fault Momma nature too much.
If I were to wear a red vest and hat with a Robertson Red Tartan Kilt I would probably go with a dark, wine or brick Red instead of trying to find the exact color. I would try to coordinate my vest and hat with the rest of my outfit. Jacket, tie, and hose. (again, coordinate but not match)
I have one guideline I try to follow as much as I can. Coordinate the rest of the outfit. Then let the kilt stand on its own.

I wear the kilt because: Swish + Swagger = Swoon.
