Albino?

["Cathleen Caron" <CathyC at weider dot com>]

Hello!
I am a beginning birder and have been enjoying your website for awhile, but now I have a question. Yesterday I saw a bird at one of my feeders that in shape and form looked like my regular house finches, but this bird was completely creamy white in color (like vanilla bean ice cream). Has anyone else seen this? Could it be an albino finch or perhaps something else (I couldn't see anything like it in my book).
