chibi & nightmare are my absolute faves ;c;

Bloodred/Graveyard are my absolute favourites with Chibi, Reborn, and Blacklight next. Not necessarily in that order.

Nostalgic is growing on me, but I'd have to say nightmare or glacier!

Glade, Angelic, Nostalgic and Reborn are my favorite pet colors. (I can't pick one, bro). [edit] You got a forum point while making a post! Check out the shop here!

Graveyard is pretty sick. There's so much detail there, like some of the pets are almost nauseating to look at and that makes them really freaking cool.

If Experiment constituted a color, I'd choose that. Otherwise, Nostalgic is really neat because each Nostalgic pet seems more individual than other colors.

Sweetheart pets for sure!! ^-^

Glacier and chibi. The new chibi experiments are perfect. :)

glade :D

Scribble. that's the best one for most pets ;)

I adore my Nostalgic Warador and probably the only color in that particular specie. Otherwise I'm a big fan of the Bloodred, Nightmare, Angelic, Storm and Reborn -

Spectrum, closely followed by Sweetheart. Cuties. I also really like Glade, Nightmare, Glacier, and Reborn.

Glacier! Glacier! Glacier! oh and did i mention glacier? sweetheart and chibi are pretty cute ;)

Galactic! Glade, chibi, sweetheart and graveyard are all cool though

scribble, followed closely by storm :)

Torn between nightmare and bloodred, both are just great.

It's hard to say since I usually choose pet species/color based on the personality of their character, instead of picking something I really like instead. I think I'm going to say it's a torn between Glacier and Reborn, though - there's something about their art style and personalities that is incredibly appealing to me, and I find them the easiest to work with out of all other non-colorfill pets!
