I recall hearing that some brands of water heaters had problems with inlet screens clogging up with dirt. Seems odd to be both units, but could be from similar conditions-construction debris, unvented dryers.

Were the water heaters off when you arrived? If so, and you fired the pilots up and cranked the burners, that's the color you'd get from condensation/ moisture in the burner compartment.

Also, if you didn't wait several seconds or so before checking out the burners, then that's the color you would get.

The other common issue would of course be the primary air intake "grate" being plugged, as mentioned.
