Over several weeks throughout 2010 Finch observed the ever changing tone and color of the English Channel. He then selected a pantone color swatch for each moment observed resulting in a palette of 100 variants of sea color, which was used to dye 100 flags. The four existing flagpoles at Christchurch Gardens were used to hoist a different sea-colored flag every day. The color of each monochrome flag was determined by an observer of the sea every day of the Triennial following Finch's swatch. The flag hoister chose the corresponding flags and raised them at midday.
