Hello! My Question Is: I Am Currently Taking Lisinopril And

Hello! My question is: I am currently taking Lisinopril and just got a new refill. The refilled medication looks nothing like the previous medication I was taking, and when I look it up in the pill identification there are no images that match my medication. I am taking 40mg and the pill was usually white, this time the pill is smaller light green in color. Should I take the medication back because I have never taken this medication in a green pill and am afraid I may have been given the wrong medication
