Another question about clans--adopted children

[Dale Seago]

Where on earth do you get this idea from,it's complete nonsense, whilst there are instances of finer cloth being used for wealthier people or perhaps an unusual colour for a special person, the idea that you can classify tartans or wearer of tartan in this way is just another one of the many romanticisms and are simply without credibility and shouldn't be broadcast as fact

That whole color-scheme thing rang a bell and I was pretty sure it had to do with ancient Irish society from before the Gaelic colonization of Scotland; so I did a little looking around, and:

We are told in our legendary history that exact regulations for the wearing of colours by the different ranks of people were made by King Tigerumas (Teernmas) and by his successor, many centuries before the Christian era - a slave was to be dressed in clothes of one colour; a peasant or farmer in two; and so on up to a king and queen and an ollave of any sort: all of whom were privileged to wear six.

At the present day green is universally regarded as the national colour; but this is a very modern innovation, and as a matter of fact the ancient Irish had no national colour.
