A lot of morphs are very subtle, like spotnose, fire and yellowbelly. Not quite as "in your face" as say a lemonblast, spider or pied. The real potential with a lot of the more subtle morphs lies thier genetics and what they can produce.

For instance, yellowbellies and fires aren't too much to look at in thier heterozygous form, but when they are bred together to make a super (homo) form, they are quite different, producing ivories and black eyed leucistics respectively. Same goes for lots of morphs.

That said, a lot of them cannot be appreciated in pics on the internet. Seeing them in person makes a big difference.
