For...research purposes >w> Please help me out I really need this info today as soon as possible~!!!

What order did the subeta pets come out in? I know the Kumos was the first ever pet, but what came out after in order please? ALSO. What colours came out in order after "Common" colour for the pets?

Does the Subeta Wikia say?

I've been here a long time, and the pets that are last in the Create a Pet page all look like the pets that have been created since I've been here, excepting the Bhakoru Bumbus and Neela. Bhakoru Bumbus and Neela are in order of appearance, but I do not know where they fit in with the others. I also would not be able to place any of the Experiments.

Scribble Steamwork Common Nightmare Nostalgic Blacklight Sweetheart and Storm are the latest colors as best as I can remember.

I think they're in order on the pet creation page, minus some of the ones that you have to obtain other ways. The first six listed are all pets that were originally drawn by Eevee1.

This site might interest you/help you out: http://www.pausedlife.com/subeta/species but unfortunately they stopped updating in 2013 and I don't see anything before 2006.

Wow! you guys have helped me sooo much D: Thank you!

you are welcome, sorry we didn't know more, but at least that's a start for you. Another site that used to (and may still, but my bookmark is a different page now?) track colors and when they came out was Neocolours (the british spelling) they did both Subeta and Neopets.
