Yellow tourie preferred?

[Dale Seago]

". . . making ones "tourie" yellow instead of red wool, the former as everyone knows, the favourite colour of the Gael."

I suspect this "favorite color" bit may actually refer to the Gaels' preference, up into at least the 1600s if I recall correctly, for saffron-dyed leines/shirts. That shade of yellow does seem to have been something they were fond of.
