The order of color on the hue circle has 2freedoms; clock/counterclockwise. To recover the degeneracy, a complex color solid {Ψ(z)} ; z=(x, y)+ iY is proposed, wehere (x, y) and Y are usual quantities in CIE ordinance system. The {z} is shown in Fig.2,a substitute of invisible {Ψ(z)}. Thus, the hue-circle' freedom is absorbed in the spin of new color solid. Supposing the solid is put in an interactive space, the spin vector S must be forced toward the outer field, just as a magnet does in magnetic field. The same idea would be applicable to harmonism in such a way that when spin and space belongs to same orientation, then the both may be stable together. Let's think about the case of male-female screw fitting. Next step is to find a differential equation to determine the Ψ.
