If they were dark brown/green with striped and as they grew they bacame yellow in patches slowly spreading all over then they were probably not dyed and this was the tansition between juvie and adult colours. If they were a solid light green and slowly became less green and more yellow then they would have been dyed.
This is what a BP looks like as it changes from juvie to adult colours.
