The only 4-color camo pattern in official use in Germany in 1974 was the experimental M.A.S.S.T.E.R. pattern, also (incorrectly) known as 7th Army pattern.
Some units kept using this pattern even after the new MERDC pattern (above, in M813rc's post) was introduced in 1975.
With its large sand and rust brown colored areas, the MASSTER pattern was not very effective in Europe. There was no variation in colors for different backgrounds for this pattern.
Sorry, I don't have a picture.
