Why yes, there are! It kinda depends though... for example, a cobalt blue Bromo Seltzer is extremely common. An original in clear or aqua would be special. A cobalt soda bottle, on the other hand, is much more sought after than it's aqua comrades.. this is a question not easily answered, you're gonna have to do some homework.. []
Ok, yeah i've really never dealt with marbles before and my last dig i came across an all white one and then today i found an white marble with orange swirl.
Well, I screwed up there.. I didn't realize this was a marbles forum topic! I look at "Today's Posts" and assume they're about bottles.. very very silly me!! [] Please accept my apology. Marbles? I will let others expound on them.
