Feileadh Mor tartan as camouflage?

[figheadair]

The belief that natural dyes are dull and chemical are bright is a misapprehension of the process and the nature of the chemicals.
Natural dyes ARE chemical dyes, just chemicals that appear in nature. Modern dyes tend to be lab chemicals. Either set can yield
both bright and dull colors, per the choice of the dyer. Another major factor is the mordant used. The same dye on the same fabric
can yield completely different colors, or different hues of the same color by the use of a different mordant. Or the same mordant
with a different pot. Or no mordant, just a different pot, in which case the metal in the pot can act as a mordant. Very old and
sometimes complicated technology, but no less effective than how it's done today. Easier today, maybe, but the old ways still work.

And to illustrate the point, these shades were all produced with traditional natural dyes.
