 Even though the CIE $L^*a^*b^*$ \cite{cie86colorimetry} color space

+random colors (cf. \cite{healey96choosing}):
 using a uniformly chosen hue angle
 produces too much blue and too little yellow 
 for high $L^*$.
 Because of this, we use a different color circle
 with seven evenly spaced ``primary'' hues (RGB, CMY and orange).

+% - notes regarding color naming study result table:
+%      - orange is clearly perceived as a distinct color
+%      - a large range of hues is perceived as blue
+%      - many different names for hues of magenta (pink, purple, magenta)
+% - a maximum of seven colors seems to be easily discriminable;
+% - the 7 colors reached by maximising discriminability are in fact
+%   very close to our RGB, CMY, orange colors
