Essie describes Merino Cool as a sensuous autumn mulberry. Personally I'd describe it as a purple-greige. Shopper Drug Mart was having a sale on Essie polishes last week from $12CAD to $8CAD so I picked up a couple of shade and this is so far my favorite.
This applies like all Essie polishes, a bit thinner than OPI or Julep and you definitely need two coats to achieve the bottle colour. I found that this turned out darker than what the bottle appears and more purple toned than I thought. When I was in the store it looks more like Smokin' Hot does in the bottle.
I do however love this colour, it's fantastic for fall/winter, not too dark like some polishes but not too bright either. I'm really loving neutral-ish nails lately and merino cool fits perfectly.
