Answer: If the fruits are off-color, they will probably be aborted soon; a purplish/brownish cast almost always means the fruit has dried and died on the inside. This could be from lack of pollination, it could be weather related, or it could mean the tree suffered through droughty conditions at the time the little fruits were just developing. The funny thing about citrus trees is that they can look perfectly healthy one day and the next day develop yellow leaves or drop all their fruit. It has to do with cultural and environmental conditions. As long as you water your tree as often as necessary to keep the soil moist but not soggy wet, you feed (with a specialized citrus food in amounts and as often as suggested on the fertilizer label), any you provide as much sunshine as possible, your tree should thrive. Best wishes with your lemon tree.
