Could someone explain to me then how extra curves and extra 
blending isn't touching color mixing ?  I can understand it 
for split toning but there one hue is replaced by another one 
along the tonal scale.

Joost indicates it more or less in his first message:
"Since I can only interpolate between two curves I can only 
create tones at the boundary of the color space".

Either the new blendings do not cooperate with one another 
(adding just another straight line) or they together describe 
a slice of the color space in a crude way (an area) or you go 
the whole 3D way and use a color engine.
