There are tons of coloration variations, however few of them are specific to a particular type of uniform. The so-called Belize type is only found in the 1980s Tropical cut as far as I know, which makes it rather unique. Most of the other variations are spread all throughout the different models of uniform. However, each model tends to have a defining coloration. One that is more prevalent than others.
On top of the standard temperate combat uniforms each major issue of uniforms (P84, S95, etc.) there were sometimes tropical, arctic, desert, helicopter, sniper, para, windproof, rain gear, and probably other stuff that isn't coming right to my head. P60 and P68 were just basic uniforms AFAIK.
Even further, the S95 Desert uniform underwent several modifications without a re-designation, apparently. I've got 4 variants. Two different style of buttons, two with shoulder epaulettes, one with only a chest epaulette, and one with both shoulder and chest epaulettes. I have no idea how many variations there are.
Lastly, some of the tropical uniforms were made from different cloth, but were from the same era. There is the tight cotton/poly weave (common) and the "teabag" weave (uncommon).
Yup, there's enough DPM stuff out there to drive even the most sane collector insane
