The babies will come when they come.
Most of my does have given birth on day 32, though I can remember one doe that always gave birth on day 30. In my rabbitry, I have had a few very large litters that came as early as day 28 or 29; there actually was one litter that was born on day 27 that survived. If a doe is carrying a small litter, she may go longer - to day 33 or later. Generally speaking, if a doe carries to day 34 or 35, she is often carrying only one or two, and the babies grow so large and the doe takes so long delivering them, they don't survive the birthing process. That isn't set in stone, though - I have even had a few of these overdue babies survive on occasion. I have heard people tell of litters born as late as day 42 and survive; I haven't seen this myself, so I though I suspect some type of delayed implantation, I really don't know what might have been going on.
My rabbits have given birth at any time of day or night. I have been in the rabbitry many times as a doe has given birth - I remember one doe that I had forgotten to write down her due date. As I just walked past her cage one morning, I looked at her, and she was standing with her forepaws on the cage door, with her mouth full of hay; her eyes were screaming, "
GIVE ME A NEST BOX!!!" I did, and within about 20 minutes, she had some fat little wrigglers in her nest box and was recovering in another corner of the cage.
My bad.
As for colors, with both parents broken, you should get a lot of brokens, but you could get solids, too. As Zoomie said, you have a lot of possibilities just with what you
can see on the parents, though I often joke that if there is a color that you are hoping to see, it will be the last that happens for you, or it will be the baby that gets pulled out and dies on the wire - rabbits seem determined to frustrate us.
With both parents Lionhead crosses, the babies will be all over the road on manes as well. You can get babies without manes, or with single manes like their parents. You can also get babies that have double manes, and they will go through a stage that looks really weird - they will have a triangular cape of fur growing on their backs, but nothing visible on the sides, when the others are pretty fuzzy. Not to worry - that is normal for a DM Lionhead.
