ONR Change or is it just the colors?

[PhaRO]

I have been using QEW for a while. I ordered a quart of ONR quite a while ago and it was a grey blue color. About a month ago I ordered a gallon and received 4 quarts grey blue color. This week I ordered another gallon and it's a brighter color green. Obviously the color is different but has the product changed?

It is still the same product, David (owner of Optimum) changed the color so it doesn't turn anymore. It didn't effect how the product works at all.
