1984 Topps Football Question

I was just going through a box and noticed that the card number for 155 Darrol Ray was brown in color as opposed to green like every other player card in the set. Just wondering if they are all printed like this? Would anyone mind checking? And yes, I have a lot of time on my hands.
Thanks.
Thanks.
