Which are the other contrast pair of colors other than Black & White contrast colors?. If yes, can these colors be evaluated for Zebra crossing on road?. Thanks & Regards, Prashant S Akerkar

Google. Think about colour blind people and other colours used where there's traffic.

Any pair containing one secondary and one primary colour are contrasting colours if and only if they are on opposite sides of the figure. For example, blue and orange are contrasting colours. As are yellow and purple.

Prashant, it seems that you are not willing or able to post sensibly and ontopic. I'm giving you a nice long break. I hope you are able to find the answers you need elsewhere.

That is a good question. Yes the picture above is very helpful. If you mix red and blue you get purple. If you mix red and yellow you get orange. If you mix yellow and blue you get green; Now you see how they are contrasting. All colors are produced by the three primary colors, blue, red and yellow. The equal parts of yellow, blue and red combined create black. yet white is the absence of color which was disputed at some time but true. You cannot make white from red, yellow or blue. Though pure white light can be broken down into the three primary colors from Newton's great invention the prism. which was stolen from him. Colors are listed in tones and shades, which incorporate different amounts of black or white mixed with these three different primary colors. There are also what are referred to as opposite colors, though I have never heard of opposite shaded other than black and white. I have never heard of opposite shades of gray or tone. Look up opposite colors also, but contrasting colors are mixed as listed above I hope this helps you. I come from a line of artists and engineers.

One funny fact. Zebras can only tell each other by smell. I guess there is to many stripes of opposite shades to tell them all apart. It is like a racist Joke. All zebras look the same.
