ANSWER: Please refer to the following:

The above link gives a color chart showing contrast color selections available.

Contrasting color pairs are also often sought as complimentary color pairs.  Especially, in digital displays of alpha-numeric characters it is highly used to get best rendition for human eye viewing.

I don't understand the zebra question; I think zebras are always black and white.  

Let me know further your thoughts about the zebra question.

PS: See the London paper about the type of crossings compared with zebra:

QUESTION: Dear Prof Cleggsan

Thanks.

As there are many different contrasting colors available other than black & white colors, can we evaluate and implement these colors for zebra and other crossings?.

Thanks
Prashant

Answer
I suppose you could implement any contrasting colors.

For public highways and railroad crossings there would be ordinances and regulations required to be met. Don't you think?

I am sure there are studies and research projects that could give more intelligence on what colors have worked the best but it is an area I have not expertise in.  Sorry.
