Colorondo: A Game with 80 Colors

If you release a chip from one of the five coloured boards and place it on a different-coloured background, its color suddenly appears different to the one it had in its previous environment. Why is that? "Colorondo" provides a hands-on experience of the phenomenon of simultaneous contrast heightening. Pages of instructions are quite superfluous, as you don t need theory to observe the amazingly versatile interaction of colours. All you need is a keen eye and a willingness to try out different variations. There are 79 possible combinations for each of the 80 colours.
