DPD powder a little over a year old (from tftestkits) is grey and I didn't really notice it until I got my new refill yesterday and it's snow white in color in comparison.
I guess my first batch started out totally white but just over time didn't notice the change.
Is it still good? I have maybe 10-15 tests left in it I think but got a refill just to have on hand.
