In case you sometimes struggle to visualise the RGB colour space on a computer, US artist Tauba Auerbach has created a handy reference guide: a cubic book that shows off all the colours in existence.
Measuring 8 inches in each dimension, the book illustrates the entire three-dimensional RGB colour space, with each page turn showing a subtly different slice of colour. In fact, three different books exist, with the spines cut along different axes — but given their size, combined they’d take up an awful lot of shelf space. [Tauba Auerbach via Design Boom]
