The colors in the comic represent different meanings that foreshadow an upcoming big fight in Vietnam - the green soldiers symbolize envy and corruption, the grey tank represents decay and pollution, and the red title foretells of war. The colors in the suit also carry symbolic meanings - red stands for power, rules, strength and aggression, while grey denotes respect but also decay and pollution, hinting that Tony Stark has gone missing and the others will need to search for him.
