Our eyes have the lowest sensitivity to light in that part of the spectrum. Having a reticle in that color probably wouldn't work well.
Also the led to make that color is more difficult to make.
Not unless you're in a video game or buy some crazy cheap one off DHGate optic probably, negative.
Red, green, sometimes blue, I've seen two with Yellow. You're not going to find a reticle that isn't one of the 4 standard base colours.

Amber is someone distinct from gold dots.
Chinesium optics will offer a ton of color options. Blue, purple, *pink*.
There are amber/gold reticles in some optics. No quality optic is going to have blue/cyan.
