#basically it would intercept whatevers coming from the graphics API and modify it to have less contrast if its above certain tresholds

if one exists i havent been able to find it so i want to make a program you can install that acts as a sort of post-processing filter on everything you display on your monitor to "catch" flashing lights before they're displayed and diminish the effects because i'm tired of losing hours of work due to a bad headache or spacing out from flashing lights. however developing and testing this tool would require me to watch a lot of flashing lights videos LMAO so i don't know if it's at all feasible for me to do it
