It is quite simple to do something similar. Get one of the RGB LED lamps (the color adjustable ones) and set it to white. It should mix R G and B (which do not really overlap) into a whitish shade.
If that is the only light, you will notice that red, green and blue look very pronounced. Veins in my hands are too red - scary.
The downside is that other colors shift. Orange: is red. Yellow, like the wooden floor: very dull. A lot of nuance is lost.
Now, an RGB LED is just one thing. But is is an easy and cheap experiment to perform, to see if this helps you.
By the way I do not thing the glasses would help a lot with an LED traffic light: that red is already so pure that filtering will aither kill all the red, or just pass all light of the LED through…
