Circle Packing
The truncated square tiling can be used as a circle packing, placing equal diameter circles at the center of every point. Every circle is in contact with 3 other circles in the packing (kissing number). Since there is an even number of sides of all the polygons, the circles can be alternately colored as shown below.
