Merriam Webster dictionary: a colourway is a colour or an arrangement of colours
I think it’s one of those things where the term has outgrown its original meaning! Like how the floppy disk icon is still used as indicators of saving despite nobody really using those anymore, and the term “out of fashion” isn’t restricted to specifically fashion anymore
Oops just checked the link, you might be right. It guess it does make sense that it’s the way colours are used rather than just what the colours are. The way part.
Sorry about that mate! I’ll amend the post then
