Oh, thank you for the replies!
The color I pulled out of the pack was a light purple. The gal did a scratch of it on an index card and wrote indigo, so that's where I got the color and name from.
I do thank you for all the suggestions, but think I am going to go with a large 10 minute block with the light purple as the outside and the black for the center diamond.

I'll post a photo in about a month or so when it gets finished.

Hugs,
