I went into The Met's archive expecting to land on something sculptural, and instead got stopped cold by a landscape. I picked this one for the color. Church painted the whole climate range of the Andes in a single frame — tropical green at the bottom, snow at the top — and none of it looks invented. The greens, the haze, the light coming through the falls: it's all natural color, mixed the way weather actually mixes it. That palette became my entire brief.
