Colors are not wavelength. Color actually has three dimensions that can be coded as RGB, HSL, LAB, or using degenerate coding in four dimensions with CYMK.

Visual geometry has three dimensions, making vision a 6 dimensions thing (plus time, but that is added to every sense).

You point still stands though, since AFAIK smell has many more dimensions (not sure if they've been thoroughly counted).
