Why do red cars and some other red objects look yellow orange through the red lens of 3-D glasses?

Question

But the red stoplight looks red through the red lens of 3-D glasses?

No, for the record, I did NOT drive with 3-D glasses. I was a paasenger in someone's vehicle when I noticed this today.

Answer 1

I believe it's the tinting of similar colors.  I suppose when they mix together, the red's are of different hues, so they don't blend with the standard red lens.  It could also have something to do with light passing through.

Answer 2

It would probably have to do with the material the 3-D glasses are made of and, of course, the right tint of red.

Answer 3

It's to compensate with the 3D illusion.

Answer 4

i think that's because when we loosen the red light into the main colours that is made of, yellow and orange appear to the sight (i mean the 3-d glasses may work like the encyclical).

that's all i know, i hope i helped you.
