Epoxy primer activator-- should it be clear in color, or...?

#1
I have a quart of SPI epoxy primer activator that I opened maybe 8 or 9 months ago and used maybe 20% of. Now I have another job to do. For the life of me I can't remember if it's supposed to be a clear liquid or golden brown, as it is now?

The activator will turn darker over time. I have not had any problems with it working properly though but then again I use the black epoxy and don't see any color change.

when its new its never really clear but it has a tea look to it. as it ages it get darker and darker red in color. doesnt affect anything and will work just fine.
