Have not seen the C&B in person, so this is somewhat speculative..................
In the second link to the PB site, look around a bit, that one is newer, see here:
The first link is an "EZ" & pretty much just like the one I showed.....lighter, but still nice, rich Blue........
This is Brian's Mesa Azul, older ones, somewhat lighter.....
He will tell you though, that there's a pretty wide variance in the color, but I'm pretty sure, generally speaking, the newer ones are darker......
