If blue-green is placed between yellow and green, what is its correct position?

Correct answer: Between blue and green

The governing rule of the colour wheel is that a tertiary colour is positioned between the two colours named in it. Blue-green contains blue and green, so its correct position is between blue and green. Yellow-orange would belong between yellow and orange, while red-orange belongs between red and orange. Thus placing blue-green between yellow and green confuses one of its components with an unrelated neighbouring colour.
