  A recently announced discovery by LHCb of a doublet of overlapping pentaquark
resonances poses a question of what can be the origin of this doublet
structure. We attract attention to the fact that such degeneracy could
naturally arise if constituent "baryon" and "meson" were in the colored rather
than colorless states. This is an appealing possibility, also because in such a
case the pentaquark state would be no less "elementary" than the other hadrons,
and would provide a chance for essentially new non-Abelian chemistry.
