do snakes see in color?

[Minkness]

I was tbinking that it would be very neat to have a brightly colored snake such as an asian vine or a green grass snake in an enclosure with very dark, fake plants. Things like a black back ground, dark purple/magenta plants, black/brown climbing sticks or rocks.

I wonder if that set up will be ok to showcase that lovely bright green beauty, or, would being so 'visible' even with alot of coverage, be stressful on the animal?

Same would go for brightly colored aboreal lizards.

I know 'natural' or 'sanitized' looks are generally preferred, but was just wondering how this would affect the inhabitant.
