Your potassium bromide looks weird too; mine also has some discolorations, but that's because of minor contamination with developer compounds which oxidize and give a brown coloration to it. The potassium bromide itself should not change color. Hence, I suspect yours is quite severely contaminated with something that oxidizes.
I don't know what's going on there, to be honest. If you mix a small amount of developer this way (accepting that it turns weird colors), does it actually develop paper at all?
