My Jack's Parft B isn't blue? Anyone else?

I got the 25lb bags of Jack's through Amazon & expected the Part B to be blue but it's white. No blue dye.

Isn't the dye copper sulphate?

Isn't the dye copper sulphate?

I have no idea. I left a message with the company and sent a question to the seller as well. The product display read something like "same great product, new packaging" but I wouldn't expect the product color, a feature, to disappear.

Don't know about Jack's but when looking at fertilizer, which is what it is, straight up agricultural fertilizer the colour is for factories that make various fertilizer so use colour to distinguish, helps their customers too ! If coming from another source they may not use it.
Or it's a mistake ???

I called the mfg. It's legit stuff. They stopped putting the dye in the Part B. They reccommend buying directly from them, J. R. Peters since they have no control over the Amazon distributors.
