If you use iOS, there is a Color Filter option, in Settings > Accessibility > Display & Text Size > Color Filters. You can select Red by choosing Color Tint, and pushing the Hue slider all the way to the right or to the left (that slider wraps around the hue angles), for example. Here is a tutorial that I found:

It does not do everything you want (i.e., it does not turn the image into a completely red-monochrome image), but it might keep the bugs (the flying kind) away.
Move the Intensity Slider in Color Filters as far to the right as possible to mimic a red-monochrome the closest.
With a Color Filter, the iOS display may look better under Light Mode than Dark Mode (under Settings > Display & Brightness). You just have to try and see which you prefer. And perhaps turn off TrueTone also.
It might keep the flying bugs away while you surf the web too :-).
