The top one is patternless. As they age they loose all traces of pattern and are a yellow/orange as adults. The middle one is a mack snow. They do have blue tinted eyes but that goes away with age. They can also be very dark. Adults have very little yellow in them and the best lines retain there purple color as adults. Having seen lots of both morphs at Petco that's most likely what they are. As for a price patternless go for $20 or less and mack snows go for $25 and less at shows. I hope this helps you.
