Powder is usually grey because it's coated with graphite to make it flow better .Perhaps yours isn't . However when powder deteriorates it can turn orange or redish and should then smell not of the normal solvents but an acrid or ammonia smell. That's no longer safe !!! If you have any doubts , dump it !!
