These photos, taken about ten days apart, illustrate darkening of the comb as well as the effect of the metal in the wiring on larvae in new comb on wired wax foundation. They also show the initial brood area and how it is out of phase with the outer ring, laid later.  At any given time each area is empty, then capped, then empty, then capped, while to he other is the opposite. Also, failed cells in each area fall out of phase and stay out of phase as well or are filled with nectar and/or pollen. This would seem to be a good queen with good bees on a flow. It is obvious that any cell that fails to go a full cycle is cleaned and laid or filled again immediately.
