Color samples taken by eye at various sites around the southwest of the United States (sample images: “New Colonial Yellow” is the color of uranium deposits at the Laguna Pueblo reservation in New Mexico, where uranium was mined for nuclear weaponry past and present; “Pool Party” shows polluted pools at the same location; “Rosedust” depicts the tourist site four corners). The collected samples were arranged by location so that each vertical band represents one site in linear time order, with color from sky to ground. The composition was then re-photographed, and projected onto half-silvered glass as a projection of memory.
