I was recently told about YLI 100 silk, I have not used
it but it looks very promising. I think it a US product, there is
a manufacturers web-site. It gives colour charts with ref # only.
I found this supplier in the UK -

You'll note that they give the shades names.
I'm sure with a little searching on Yahoo or Google, it would
be possible to find a supplier in the US.
