This optical brainteaser presents a unique and fun challenge
that can be used to teach the basic dimensions of color: hue,
value and saturation. The 64 colors on the cube are combinations
of cyan, magenta and yellow. Each cube is made up of 0%, 33%,
67% or 100% of the three colors. As you arrange the 64 smaller
cubes to build the large cube, your challenge is to find the one
truly harmonious solution to this puzzle. Instructions, color
poster and color guide included. For ages 10 to 110! This is a
great combination of art and science! Made in Canada.
