Desiccant turns pink

[truck]

My air drier started out dark blue and is now showing some light pink. Just how pink will it get or should I let it get before I change to a fresh drier?

I re-use them, I place them on tin foil at 250 degrees in a toaster oven, only takes 10 minutes at the most.  I also have a quart of them I bought that I haven't even opened up yet.

Dry it or change it now. If you let it go all the way pink, you're too late, and you're already pumping some water into your tank.

I always dry them whenever I see any pink ones myself, that way I have the best advantage for getting the best dry air.

I replaced the dryer with a new one and also dried the beads in the old one in the oven. They turned white instead of going back to blue so I don't trust drying them.
I ordered new orange beads this morning and I will just change beads when needed.
