CiM Troi, a deep, opaque blue-green. It comes up very streaky, which I like, but may not be your cup of tea.
Three spacers in Troi, with the middle one with Eff 276 Dark Ivory dots. You can see there is a very pronounced reaction with the ivory, and the dots sunk into the Troi and got all malformed instead of staying round.
I thought it looked like an exact match for CiM 586 Mermaid, except the Mermaid is not so streaky. The malformed blob on the right is Mermaid.
Other folks however are reporting that it is more like Cotswold Blue and not this close to Mermaid. So, as always, your mileage may vary.
Does that phrase even mean anything to anyone any more?
Troi - streaky version of Mermaid in my books so far.
