Hot pink isn't a frequency. It does not appear in the visible light spectrum. You can only produce it by combining multiple "impure" frequencies. You generally produce it by combining a spike of low-frequency red with a spike of high-frequency violet.
Human eyes try to "triangulate" a complex spectral analysis into an absolute position in a colour space, that colour space is the surface of a sphere or torus or something, and hot pink is "between" red and violet. Three-coordinate colour space is very much an artifact of humans, and how human eyes/brains work.
