So after I took the peacock feathers off and wanted to try something a little darker under the Barry M 288. I tried it over Essie Merino cool and I am loving the results. Barry M 288 is a very fine glitter - maybe glimmer (mixture of glitter and shimmer) in a clear base.
In the bottle it looks like it should be a metalic foil on the nails and when I bought it 4 years for a christmas party I was very disappointed that it wasn't a full metallic. I'm so glad I found it again.
