According to a study by researchers at Ohio State University, colours tend to be divided into eight main categories: red, green, yellow/orange, blue, purple, brown, pink and grue (green/blue) across many languages. The categories are remarkably consistent, though the boundaries between the different colours vary from language to language, and some languages have fewer words for colours, which are often amalgamations of the main categories.
One distinction made in all languages is the one between ‘cool’ colours, like blues and greens, and ‘warm’ colours, like reds, oranges and yellows. Some languages use a single word to desciber the cool colours, and a different word to describe the warm colours.
An example of a language with different colour boundries to English is Welsh. The Welsh word glas represents a blue/green/grey/silver colour, llwyd is brown/grey colour, coch is a redish-brown, scarlet or crimson colour. The other Celtic languages have similar colour boundries.
