Different colors means different representations of the small group of k. Different lines have different point groups so coincidence of colors on different lines has no meaning, but bands with the same color on the same line (for instance along delta) belong to the same representation. So for instance along delta all the red bands belong to the delta_1 representation that means that the wavefunctions are totally symmetric, all the blue bands belong to delta_5 so are two-fold degenerate ecc.
