Why is this concentrate so dark?!

Why is this concentrate so dark?! ( stoners / _NikNatNot_ ) Got a new plug and usually the dabs are good and nice and yellow of various consistencies but this one’s kinda like hmmm? It taste fine it’s just so dark😂 idk I usually am accustomed to shatter wax but here recently I’ve been dabbling in new concentrates and I haven’t ran across this. Is it just bc maybe it was left in the light or something or maybe is older possibly? Is it still good I mean I still feel a nice high and it taste okay colors just off. #NoDumbQuestions why,this,concentrate,dark,why this concentrate,dark
