> A wave has a frequency. There is no concept of "color" associated to a wave.
Funny because when I explained radiant heat to my daughter I used it as an example of light, but infrared is a color we can’t see (but we can feel the light the same way we feel the sun on our skin). She asked about other colors and I went into ultra violet, X rays (a color to which we are transparent), gamma rays, and so on.
Yes, you described her how a wave interacts with her body and creates sensations (heat, colors, ...).
This is absolutely true, but the wave does not carry any of these sensations on its own, it is its interaction with sensors/receptors in her body that creates it.
Like I said elsewhere, a color is like pain - a needle does not have any "pain" in it and a couch hit with a needle will not create "pain".
