Charles-Edouard Jeanneret was known as Le Corbusier. A Swiss-French national, Le Corbusier became famous for his modern approach to architecture, designing buildings and spaces across the world using new materials such as concrete. Art school trained, Le Corbusier designed spaces for living, in a bid to change the typical crowded cityscapes he came across in his travels across Europe.
In 1931 Le Corbusier came up with an architectural colour palette which he used to create a sense of space and harmony inside and outside of his buildings. The system is laid out as a sliding colour chart, consisting of 12 pages, where you can create colour combinations by sliding across the centre to reveal different colours to pair up with the header and footer colour. The Le Corbusier website has an interactive version which you can find here. There is also a nice video of a copy that came up for auction on the Co Design website.
This apparently simple tool demonstrates how a visual colour chart can be really important to designers when making choices about colour within their work. The colours still resonate today, despite an updated version being produced in 1959 with a reduced colour set. It feels very similar to many of the colour combinations offered by contemporary paint producers such as Farrow and Ball
