Nice frame. Food and room to lay for the queen.
This was a new frame last year. The upper corners are nice and white. Brood comb where the brood is being raised will turn dark brown with time. This is normal.
The dark color comes from brood debris that gets embedded in the wax.
Brush off the dead bees. The bees will clean up the rest.
A little mold, the bees will clean it up. Notice the pollen in the cells. ( Brown muddy looking) The bees will need this to build up the brood.

My response:
Hello
No queen excluders until you are going to divide. You need 8 - 10 frames of brood (bees in all stages, eggs. larvae and capped) to be able to divide a colony. Most divides happen in May. I will have queens available May 1st.
There can be a rare occasion the a hive is so full that they have to be divided a little early, if you absolutely have to divide in late April, I may have a queen for you.
The hives will unlikely swarm this time of year.
The dead bees on the bottom board is normal.
The bees will clean up that mold. Brush off the dead bees off the frames the bees will clean up the rest.
Your frames look fine. The nice white new combs will get darker with time and will end up a very dark brown. This is normal.
Make sure the bees have enough feed. They will use more during brood rearing. Don't overfeed. Just enough to keep the going.
It sounds like you did a reversal. Maybe a little early, but if it is loaded with bees you probably are ok.
If the hive isn't boiling with bees I would hold off on reversals for a week or so. On a three deep hive for a reversal I like to move the bottom box to the top and move the top two boxes down leaving them in the same order.
