I suppose that makes sense, I consider myself an artist and I love working with paint. An important part of painting is matching colors up perfectly (especially if you have to remake a color) and working within hues.
Hey, I know that one! My husband works in the furniture industry and he makes all his employees take the Munsell test since most of them work with stains, colour sampling and testing. But, he uses this one --------> Farnsworth-Munsell 100 Hue Test .
After taking the test many of his employees didn't know that they were 'colour blind' in certain areas. Blue/green is usually the most common area to get confused on.
