Normal Color Poop??

Hey guys, so this is the 2nd time my llittle one (3 weeks, will be a month on Tuesday) has dropped a number 2 and it had been this texture and color. It's looks more green in the picture now that I look at it but in person it seemed more grayish than green. The last time he did this was probably a week ago. His bowl movements between them and now have been the normal yellowish green and mushy/seedy. Is this normal or should I make an appt with his pediatrician? Thanks in advance.
