OPI Maine-iac Mauve

This is bizarre. Is Maine-iac Mauve purple or brown?

Maine-iac Mauve is a discontinued OPI colour. I bought it because the swatch appeared to be mauve with golden shimmer as on the right. However in natural light, it's frosted cocoa with no shimmer.

The colour is neutral so I'd wear it if I can't choose a colour. I think it's understated and complex. I'm looking at in on my nails now and it's plummy taupe. This is a colour with mystery...I like it!!!
