Please note that this is my interpretation of the note about a four-colors scheme, I am not the original author and so I may have misunderstood.

Here is a render from a Raumschach implementation for Table Top Simulator. It uses a four-colors scheme.

Opening the picture you can see that the two boards with a white corner have a different color scheme than the three boards with a black corner. The two boards are green, the three boards are brown.

With such colors when you move the Unicorn you have that if you go between green boards or between brown boards the square color will stay of the lightness level — start from a dark cell and arrive to a dark cell, or start from a light cell and arrive to a light cell. But if you go from a brown board to a green board or vice versa, then also the lightness of the cell will change, when the Unicorn starts from a dark cell arrives on a clear cell or when it starts from a light cell arrives to a dark one.
