Baby Poops color

My LO now is 7mth, he got diarrhoea from last Thursday until Saturday, Sunday already recovered, but Sunday morning I saw his poop color is like clay green color, and these two days his poop also green color, he didn’t eat any green leafy food, is there anything I should take note or when should I bring him to see doctor? He didn’t show discomfort, still active and playful at all time. TIA
