Novel about a woman weaver/dyer in the ancient Mediterranean

[frs56]

I'm looking for a book I read 10+ years ago. It was a large format book (not large print, just larger than the airport paperback.)
The main character was a woman who worked with fabric for the royals (I'm thinking purple, but it could have indigo)
I'm thinking she was either a Dyer or a weaver.
The book was set in ancient times and I'm thinking it was in Istanbul but it could have been Greece. I do remember it was a coastal city. The original purple comes from the phoenician city of Lye, so it could have been there.
Thanks in advance.

Is it Gillian Bradshaw’s Imperial Purple?

Thanks!

Hmm. This could be it. I dont recall that much of the plot and I dont recognize the cover (but I had a paperback, not the hardcover depicted on amazon. but the situation of the weaver sounds extremely familiar. My mom was looking for it and l get her to check it out.
