Equal distances on the x,y chromaticity diagram did not correspond to equal perceived color differences. Indeed, this drawback, which is evident in the excessive representation of green and the bunching of red, violet and blue hues into the corners, has always been the subject of criticism. The difference is also shown on the graph in figure 13. Returns a colour.
