What colour is it? is a watch that takes inspiration from a concept presented at whatcolourisit.scn9a.org. The background of the watch face displays the colour that represents the time, according to the webcolour-value.

The display is a sheet of e-ink that will make the battery last longer than a traditional LCD-display since it's only updated once every second. The locking mechanism uses a small notch in the top casing which latches into the bottom part.
