Actually yes. After a fashion. Kinda sorta. There are several decal makers who sell German four and five color lozenge. There is one company which makes the large hex lozenge for bombers. They all come with both upper and lower colors and include rib tape, which was usually blue but sometimes red. All include very detailed instructions.
This site gives a fair overall description of hex camo types.

Most lozenge was pre-printed fabric (as were the two-tone streak patterns later in the war), but I've seen one photograph of a flying boat that had hand-painted hexes. Some companies applied it span-wise, or running the link of the wings, some applied it chord-wise, running from front to rear, and some put it on diagonally.

The colors are the subject of much controversy, as are all WW1 colors.
