Solid Color Great Kilt?

Solid black?

I particularly like the look of black kilts. There are sheep with black wool, so, a black wool kilt could exist using period methods.

The natural dying processes of the period made black a very difficult color to make and maintain (it would typically quickly fade). This is at least the reason given for why many Ren Fares reserve black for the nobility only.
