I get a few commons that are colored like the ones on page 4 and 5. I wouldn't consider them albino though. I have had three commons that are the exact same color as your alligator snapper.
:Sorry Gamera for answering too but have you ever checked out this link? :http://www.chelydra.org/albino_pg.html :At the very bottom it shows a good picture of an ally snapper with a pretty white shell and white head. But not pink eyes. It also shows a better pic of what my ally snappers look like. Since the ones Accomplice sent in for me look kinda fussy. They came out better in the gallery though. I guess cause their smaller pics there. Now my Ally Snappers don't have a white shell they have more of a light tan colored shell.
