Waited a couple days to see if anyone else made the following comments-don't enjoy fussing with this keyboard.
Crimson is very dark nectar, while other clovers are quite light. It dosn't take much dark honey to pull the aggregate color down in a hurry. Try a drop of ink in a glass of water, then see how much water it takes to make it clear again. Locally, country folks know that dark honey can be better than light, but in the city they think honey is supposed to be light colored and it will sit on the grocery shelf for a long time. Two different years when my aggegate was very dark, bought Dakota light by the drum to bring the color up. With 2 to 1 light it was possible to bring the dark honey up to almost acceptable. Still dark, though.
Cotten honey is very light but granulates rapidly. My bees ignore cotton,but 40 miles south of me they can get cotton honey. Wish I knew why.
