Sandcastle is a light-medium gold with warm undertones and a sparkling, metallic finish. It had good color coverage that had a denser, almost wet consistency. There was a noticeable amount of sparkle in it, which was expected as it was a Sparkle finish. I had some fallout when initially applying, and there was continued fallout during wear (what I'd describe as a moderate amount). I would advise using this with an adhesive base to minimize the fallout.
