wiktionary
From the 1610s, a compound of water + melon. The meanings refering to environmentalists and behind schedule projects derive from the idea of having green (eco-friendly, on-schedule) outward-appearance while being red (socialist, behind schedule) in a hidden way comparable to that of the fruit.
etymonline
