Some of my frames have dark areas under the comb. These were fully capped and the comb on top was light colored. Thanks in advance

I can't tell for sure looking at the picture but it could be the bees raised some brood there. Can see what looks like pollen. Neither will hurt your honey.

Thanks just wondering

They should have told you dark comb should be good luck .. and it will help you see eggs later on a little easier..
See the bees are helping you already

The center (dark cells) are from brood rearing. The outside (lighter colored) are honey cells.

I don't know why the books don't warn new beekeepers... comb changes color over time because of brood rearing and traffic. The brood comb will soon be black.
