I am not sure about the exact meaning of "pink" in English, but it is translated into Czech as ru°z`ova' (barva) "rose (color)" and here the meaning is "pale red". But the words "light" and "pale" are often confused, because the very light colors cannot be saturated. Note also that the CGA's LIGHT* colors are slightly pale.

Rather "pale" than "light".

Note that CGA's BROWN (2/3 1/3 0) is entirely saturated; and also Windows' Maroon (1/2 0 0), which I consider as sort of brown. ("Brown" in wider sense covers "dark yellow" (Olive), "dark orange" (Brown in narrower sense) and "dark red" (Maroon).) ("Maroon" is traslated into Czech as kas`tanova' (barva) "chestnut (color)".)

------ Yellow (mqdhaee strayii), turquoise (sdhnih grazha), indigo (ahgtjge yaumui), and ultraviolet (redht dhiran) are the basic colors of Jaradh, based on the sensitivity of the four Zireen color receptors. ------ The concept of 4-dimensional color space seems very interesting. It means that the hue is 2-dimensional! It is not so easy to imagine such color system, but let us try it. First, let us resume how our 3D color system looks like: There are 8 main colors at vertexes of the color cube: K (blacK) = 0 B (Blue) G (Greeen) C (Cyan) = G + B R (Red) M (Magenta) = R + B Y (Yellow) = R + G W (White) = R + G + B The hues are at the circumference of the hue&saturation triangle, so we have 6 main hues (R Y G C B M): 3 primary colors at the vertexes of the triangle (R G B) and 3 secondary colors at the centres of the sides of the triangle (C M Y). 5 of them are "rainbow hues" (R Y G C B) and 1 is "non-rainbow hue" (M). Now we will add fourth receptor. There will be 16 main colors at the vertexes of the 4D supercube: K- = 0 K+ B- B+ = B- + K+ G- G+ = G- + K+ C- = G- + B- C+ = G- + B- + K+ R- R+ = R- + K+ M- = R- + B- M+ = R- + B- + K+ Y- = R- + G- Y+ = R- + G- + K+ W- = R- +G- + B- W+ = R- +G- + B- + K+ The hues will be at the surface of the hue&saturation tetrahedron, so we will have 14 main hues: 4 primary colors at the vertexes of the tetrahedron (R- G- B- K+), 6 secondary colors at the centres of the edges of the tetrahedron (R+ G+ B+ C- M- Y-) and 4 tertiary colors at the centres of the faces of the tetrahedron (C+ M+ Y+ W-). 7 of them are "rainbow hues" (R- Y- G- C- B- B+ K+) and the remainning 7 ones are "non-rainbow hues". Of course, understanding to the Jaradh colors is more difficult, because even the 3 visible components are shifted, but at least I see now why they have 14 hues. P.A.
