Interesting, were they painted the same tricolour camo as Cobras?

Yes Łukasz, all the usmc helicopters were painted in the LCS scheme between 1985 and 1993 :

If you need more info, see theworldwars.net

From 18 April 1985 (MIL-STD-2161(AS)), the USMC helicopter fleet switched to an attractive but short-lived three-tone version of the Land Camouflage Scheme. This fit into the pattern of multi-tone green/gray schemes that were being used by the USAF at the time and which made sense given that USMC helicopters would likely operate over land rather than over sea. The LCS consisted of an irregular wrap-around pattern of Blue Gray FS 35237 with Medium Field Green FS 34095 and matt Black FS 37038. Occasionally the black was kept to a minimum, and was usually the least preponderant of the three colors. This scheme was still applied during the 1991 Gulf War although it was not uncommon for USMC helicopters to adopt alternative schemes that were typically applied in theater (see below).
