The palette
Water takes nearly half of this sheet, so its ink sets the tone of the whole poster: a deep one gives the river weight against the dense grid, a pale one lets the streets lead. Green is the other large mass, and most of it lies across the river, on the islands and the Arkansas bank; choose it knowing that it will sit beside the water over a wide area. The city side is line work: the grid along the river, the looser streets behind it, the motorways in the darkest line.
