Abstract:
We generalize previous results to dimension 5 and further. The geometry of the 5-hypercube [0,1]
5 gives a model for colour vision in the case of 5 photoreceptor types and a colour space corresponding to the combination
of five primary lights. In particular, we focus on the (topologically spherical) boundary of the hypercube
and on an equatorial sphere within the boundary, roughly orthogonal to the achromatic segment. In the polytopal
and double-cone type spaces, we consider a tridimensional hue component; in the round Runge space
we consider a 4-dimensional colourfulness component.
