To echo what others have said, here in Maine Blue Lodge ciphers are blue (and VERY small, they can fit easily into a shirt pocket let alone that of your suitcoat or tux), Chapter red though not as thick as Blue Lodge cipher books. I'm not a member of the Maine Consistory, but rather the Massachusetts Consistory, where the books are black as they are in Maine as well. My father's Consistory cipher is much fancier, being leatherbound in black with gilt edges, of course, the two colors of Consistory at least in the Northern Jurisdiction, black and gold.
While I suppose that's symbolic ("Blue Lodge, Red Lodge", etc), in size, shape, and binding I could never confuse them though the cipher for Consistory differs in some significant ways from that of Blue Lodge and Chapter, which are similar in our state.
I'll add that our current Blue Lodge cipher books have no identifying markings whatever on the outside binding or on the spine, unlike that in the picture trysquare provides upthread. As far as any casual observer would be concerned, I could be holding a small journal or a tiny copy of "Alcoholics Anonymous" printed for people with extremely good eyesight.
Only another local Master Masons might recognize what it is should it fall out of my pocket in public (I only carry it to lodge, pretty much, or to help someone study for their degree proficiency), let alone make any sense at all out of its contents.
