    If you can only see frequencies in the red range, then a rainbow will appear as a red circular band, with white light on the inside and no light on the outside.

    Pink, however, is not a pure single-frequency color, so you’d have to mix white light with your red rainbow to get a pink one. *shrugs*

    On second thought, the “white” light has to have frequencies in the orange to blue range in order to produce pink when mixed with red light.

    So a pink rainbow is actually impossible.
