never before seen cream bird!

Hi all, this was a couple of weeks ago on the coast in Wales. A solitary, finch sized, bird, hopping around on the top of a hill. It had a pure cream head, sides and stomach, with peach markings on head and back and a fawn tail, with a bit of black on it. I can't identify it anywhere. The closest we've got is a juvenile goldfinch, but it had no red or yellow on it at all. It was so sweet, like a Disney princess kind of bird, and of course the photo I got shows a small cream blur. Would be grateful for any ideas!
