Gonna throw out some bad guesses
Radiohead - Kid A (rwb album, some suggested it predicted 9/11 attacks)
Flaming Lips - At War with the Mystics (colors in album, wizard named song, politically charged album)
Tom Petty - Highway Companion (colors on album cover, American record label, self proclaimed marijuana enthusiast/pushed for legalization)
All are after 94, and are not really metal, but all hit the rock genre. Probably fodder for the not it section, but it's fun sleuthing!
