Welcome to the Forum to you and your parrots! It really isn't possible to accurately judge your Quakers' colors, or what possible mutation they might belong to, without seeing pictures. There is information on how to post pictures in the Forum Guidelines section that you may find helpful. If you do an online search for the different color mutations there will be some pictures that could help you determine if your QPs match up with any of them.
There is some variation in color intensity among "normal" green Quakers. If you look at the Forum banner above you'll see that some green Quakers are lighter and some are darker. My QP Ralph is on the lighter side. He's pictured second from the left in the banner.
Enjoy your stay on the Forum-- and tell us more about your parrots.
