Not a map or data visualization this time, but instead a tool for choosing colours. Adobe’s Kuler allows you to choose, upload, examine and obtain new ideas for colour themes and schemes. The front page features new or popular colour schemes that are uploaded by users. Choosing one brings you to the screen displayed above, which allows you to record or alter the colour values of each component of the scheme. This is useful for the often strenuous activity of choosing colours when producing maps.
