In the first version of this compound shown here, the great stellated dodecahedron is shown in yellow, while the small stellated dodecahedron is shown in red.

In the next version, each face has its own color, except for those in parallel planes, which have the same color.

Finally, the third version is shown in “rainbow color mode.”

All three of these images were created using Stella 4d: Polyhedron Navigator, software you can try for free right here.
