[Artemisia] Period Norman Garb- Black?

[Tamar Black Sea]

Greetings All,

Now for a completely different question: Does anyone know if black was a 
color commonly in use for Norman clothing?

The Norman period is not my time and place and I am pretty foggy about 
the dyes available at the time. I have been looking at the Regia 
Anglorum site for info on textiles and patterns, but I am still pretty 
vague about colors. Any suggestions?

Thanks in advance for any info or links.

YIS,
Tamar
