Dark/brownish green poop

Hi! This morning my dragon had greenish dark brown poop. Is this normal? I saw him eating a lot of greens yesterday (dandelion greens from the grocery) specifically

Oh and our beardie eats a bunch of salad. Poops almost always somewhat green. Except after bug days. Those poops are pretty damn massive and brown.
