Left to right: What's With the Cattitude?, Havana Dreams, and Riva
Below I've compared it to a couple of my other light blue polishes: Sephora by OPI's Havana Dreams and OPI's What's With the Cattitude?. Riva is very similar to Havana Dreams but is less opaque, has a slightly more grayish tone, and doesn't have as much of a bright white base. The subtle shimmer in Riva shows up with flash as you can see in some of the the photos of the bottle below, but is not really noticeable on the nails. Havana Dreams has no shimmer whatsoever. They are both beautiful, pale blue shades. I prefer the Riva, but if you are looking to save a fair bit of money, Havana Dreams is not a bad substitute! With all of these light blues I find I need to apply three coats to get full coverage without streaks.
On the end below is Sally Hansen's Blue Icing - just threw that one in there because it's blue and glittery and I thought it looked pretty alongside the others (despite the ugly label design!). It's a nice color, but it has these long, confetti-like pieces of glitter which make for a not-very-attractive, lumpy finish.
Sorry for the bad lighting in this one -- I took this around midnight indoors!

Riva is quickly becoming my favorite pale blue. Are you a fan of this shade and blues in general?
