Ah, so that's what it's called!  It worked very well for us in PIPPIN

When visiting Scotland some years back, I found that the yellow street lights removed all of the color from my vision.  I did not realize this until a car passed and its headlights shone onto a shop window - the "black & white" handbill in the window turned to full 3-color.

Originally posted by Gaafa   The yellow street lights are generaly Low Pressure Sodium discharge lamps [LPS], which consists mainly of orange/yellow [589.0 & 589.6 nM sodium lines]. The light will cause  black & white becoming that of an of an orange/yellow rendition, also causing redish ink, paint & dyes to flouresce, as with the poster. Theatre has used sodium discharge lamps in this way, one comes to mind. The Ascot Scene from My Fair Lady, where discharge sodium lamp was used to turn the costumes from black & white to orange/yellow.

The yellow street lights caused an absence of color - everything around me was grayscale except when I looked at the lights themselves - they were the only things that had any tint of yellow or any other color.  Only white headlights revealed any color in anything.
