A local app that removes blue light from the screen

Oxidative State asked Claude to build a local app that zeroes out blue and green pixels on their graphics card, leaving only red light. They've used it for a week and prefer it over night mode.

Blue light exposure from screens is nasty, especially at night.

so I asked claude to build a local app that controls my graphics card colour table.

blue and green pixels drop to zero, only red pixels stay on.

I’ve been using it for the past week and I feel stupid for using the night mode all those years.
