How do you know if D-76 has gone bad?

[PollitowuzHere]

I mixed up a gallon of D-76 almost a week ago, the powder dissolved and I got a clear yellow/amber color liquid. I've looked almost everywhere online and can't find what color D-76 is supposed to look like. Any help? Thanks!

Looks like quinol was old. Just run a test roll.
