Colourway is a word used in the fashion industry to describe the range of colours in which a particular item is available. However, there are many other ways to describe this concept using different terminology. Some synonyms include "colour palette," "range of hues," "color scheme," "variation of shades," "color selection," "spectrum of tones," and "color options." Each of these phrases may be more or less appropriate depending on the context and the industry in question. However, they all provide different ways to talk about the ways in which colours can be combined and presented in different products.
