Pentaquarks

jafuser writes "Physicists are quite confident that they have discovered a new baryonic state called a 'pentaquark' which is a particle composed of *five* quarks (4 quarks and one anti-quark to be precise). Up until now, quarks were only observed to come together in groups of two (mesons) or three (baryons). If you still haven't gotten comfortable with knowing your leptons from your hadrons, I suggest clicking through an excellent site at Particle Adventure."

Color?

I wonder what the color makeup of the pentaquark is. As I undestand it, for mesons it's red/anti-red, blue/anti-blue, or green/anti-green. For baryons it's red/blue/green or anti-red/anti-blue/anti-green. What do you do for five?
