Citrine almost looks like burnt orange. I've read it's supposed to be a dupe for the Pantone Tangerine Tango polish available at Sephora but I don't have the set, so I unfortunately can't compare. In the pics I've seen, though, they look incredibly similar.
It's a great color. It has somewhat of a jelly finish which I usually don't like, but love with this color. It's so pretty, I couldn't stop staring at my nails when I swatched it. I can't wait to actually wear it as a full mani.
Formula and application were great. I used three coats for my swatches, over a coat of Seche Vite, no top coat. The color is a bit darker than it is in my pictures.
