Royal is described as a “matte bright blue.” It’s a brightened medium blue with a matte finish. The color payoff was really lovely initially, but when I applied it to the lid, it was somewhat powdery and required some patience. I had to pat it on and be careful to only blend out the edges or else it would look faded. Milani Olympian Blue is comparable. MAC Blue Candy is lighter. MAC Electric Eel is a smidgen darker. Inglot #322 is similar. Make Up For Ever #72 is also quite similar.
