I get that... I also wouldn't mind if the color-changing items were expensive/involved a bit of time and effort, as long as I knew I could actually get one. But I think that if a site owner's going to make it so you can't choose your pets' intial color, they should at least make it at least a little easier to change the color later on -- maybe through a NPC like Misticpets had, or a special limited-time event, or something. You've gotta hook the new users so they stay and make all their friends join, you know? Frustrating people right off the bat isn't a great idea.
(And I'm not only talking about color. As Jessi pointed out, most of the ichies have really high rarities -- and the lower-rarity ones definitely aren't as cute. Obviously not everything on a site should be cheap, but I tend to think there should be a nice variety of cheap stuff before you start getting into adding a lot of pricy stuff.)
I complain a lot, don't I? Heh. If it makes anyone feel any better, I only bitch about stuff I care about.
I think this site has potential. It has a lot of neat little features (such as ichie leveling, pet chants, the different battling system, the egg hatching, hearting users, etc.) that I like.
