Whether you are producing a report, a poster, or even revising your hospital’s anaesthetic charts, colour choice is important.

Choosing colours

A colour wheel is a simple tool to help choose colours and shades (Figure 1). Analogous colours are adjacent to one another, and generally combine well. Likewise, complementary colours (those opposite one another) work. Triadic schemes are based on three equally spaced colours, while quadratic schemes use four. Colour combinations found in nature are also considered pleasing.
