This is so random, but I couldn't help sharing the information!  High-end Curaçaos, like Grand Marnier, are based on cognac (or other aged spirits), gives Curaçao a natural rust-orange color.  However the blue color of Blue Curaçao's is achieved by adding of food colorant, most often E133 Brilliant Blue.  This is not to be confused with Brilliant Blue G.  Like the average person would do this!!
