Raiding and scouting could be done with sword, javelines chiton and petassos. Riding boots of the "Thracian" type or any type of boots available.
In these case subdued colours might be apropriate.
Light cavalry service in the battle line would justify a helmet and a lance or cavalry sarissa. A spollas or a light shield could not be excluded either depnding on the mission at hand.
Clothing certainly depended on the campaighning season and the weather.

As for the weather: in April 1941 the German 100th regiment had 10 percent casualties from snow in the valleys at Belles mountains! (Greco-Bulgarian border)
My father also lost two men from his squad frostbitten in April 1949 at Paggaio mountains for the same reason.
That would give you an idea of "Spring" operations weather that the Macedonian or Thracian troops or any body for that reason had to face in this area. That might answer your question about clothing.
Kind regards
