I got in my hives today, and was surprised to see a lot of yellow wax capping. Bright yellow. Not white. I know when the flow is on the wax is white. I'm wondering what this yellow wax means, if anything. It's different from honeycomb wax (but obviously this is honeycomb wax). Honey comb wax, to my eye, is sort of that opaque-ish beige. So do we have three colors of wax capping?
