5x5 Grecian Urn 2

This string pattern has the same layout as my previous Grecian Urn 1 but with a somewhat more complicated arrangement of colors, so the side faces have four colors each. No two string fragments on the same face are the same color.

Too complicated? Here's a schematic showing how the pieces are laid out on the cube.
