Awesome 😎 now am I correct that it is a “blue” swirl or would it be more apt to call it like “blue opaque” or “blue on blue”?

Hey there! New to the marble collecting world and have recently acquired a small bag of 1” swirls, I am leaning towards most of them being Jabo due to the size and the cold roll pattern - but I cannot for the life of me hunt down any blue swirl comparison photos, and have even come across articles stating Jabo did not make blue swirls. Any help is appreciated! Thanks!
