Or else, phthalo. The tube of phthalo, dimpled metal, contributes to ‘August Nightfall’. A blob, mixed with white, indicates where winter sun went down beyond Westgarth. Another, traced with black, livens clothes of passengers to left of the floor-to-ceiling canvas. Evening itself, outside Gallery Cyanide, is a not dissimilar shade of phthalo, though rain has left sheen of sapphire on cars and windows. Take this test. Close your eyes so they see a darker shade of blue. Try not to think of phthalo. See, you cannot not think of phthalo. Open again to a gallery of recent artworks, some metal.
