Micro patterns like CADPAT, MARPAT, etc all turn into their base color over distance.

Multicam does this to a smaller degree. Multicam appears light tanish at 100+ yards which works well in brown veg. Multicam' advantage is the versatility.

Multicam works well in every environment I've tested it in, but usually isn't the best in green weeds.

If I were going to pick ONE color/pattern it would be Multicam.

ATACS FG is another good "one only" pattern, but the availability of quality gear and uniforms makes it a non starter.
