It's hard to tell from this photo but the Rubber Ducky Push UR Limits is very bright. Someone said it reminded them of Peeps Easter Candy and they weren't far off. I think this picture mutes the color quite a bit. It's not neon but it's super bright. I was hoping for more of a buttery yellow about the same depth of color as Chirp. Needless to say, I will be returning this tank. The luxtreme is very see through in this color and I can see the birthmark on my tummy through the material. I don't recall the Rubbery Ducky CRB being this bright but sometimes luxtreme can brighten a color and light luon can tone it down a bit.
Anyway, in the photo above I have laid a Citron Mesh headband (lower left) on top of the Push. As you can Citron is paler and greener than Rubber Ducky. The other headband is a Chirp Jazz Headband. The Flow Y is Macc N Cheese Yellow.
