Yellow is waterproof, white isn't. (Actually, I think the white isn't called carpenter's glue.)
Jeff But it's a dry heat!

Snowey,
Yellow or Carpenter's glue has a special binder added to it so that it bonds well with wood.

White glue: dries clear, easily redissolves in water, and doesn't sand very well.
Yellow (Carpenter's or Wood) glue: dries amber, Type I is sorta water resistant, Type II is water resistant, Type III is truly water proof, all types sand well.
Wood glue, especially Type II and III, also produce a stronger bond then white glue. Wood glues also have special additives that help them adhere to wood better. On a properly fitted and glued joint, the wood will fail before the wood glue will.
Not that it's a big deal for MRRing, but you can also get extra-thick wood glue, extended open time wood glue, and a dark version for dark wood.
