So Finally I did a Danish Rugbrot. I got the recipe on line and altered it only a little bit. It is loaded with: rye berries, cracked rye, wheat berries, bulgur wheat, flax seed and sunflower seeds. No commercial yeast at all. And no coloring.
Night before dough I added the levain to the soaker all the berries, grains & seeds minus the sunflower seeds. Here's what it looked like next morning.
Then I added the flours (AP and Dark rye). Let it rise a couple hours. Scooped into pans, let it rise another hour, then baked off.
Crumb shot It is delicious!
