Goldfinch pair?

For 2 days now I have had these birds on the ground near the feeders. From the red patch I think they are Goldfinch but I can't see any yellow on the wing. One is a lot paler than the other so I am thinking that's the female? I've looked at pictures on the bird identifier and I can't see anything else they could be so is this my very first pair of Goldfinch? Sorry about the poor photograph but it's the best I could get without scaring them away.
