The physical structures and properties exist with or without our perception of them.
Other creatures perceive colors that we can’t, sounds we can’t hear, and so forth. To claim that they don’t exist because we can’t perceive them is just silly.
The fact that certain cells in some people’s eyes reliably signal certain wavelengths of light that captures some aspects of useful information such as the ripeness of fruit does not alter reality.
If you are not a trichromatic does that change what exists compared to someone who is?
Does a colorblind person live in a world that does not posses the physics of the associated wavelengths? Does the electromagnetic spectrum in the real world stop existing for a blind person?
Clearly a high temperature black body radiating object makes all these wavelengths whether the perceiving agent has the senses to measure the wavelengths so I reject any argument that implies that reality only exists if perceived.
