As someone who didn’t have enough money to get a color monitor, I can tell you colors have almost nothing to do with dopamine generation. I played a lot of games in B&W and even used mspaint! Printed my beloved drawings in a dot matrix printer…

I think you mean to reduce distractions, not colors…

E-ink is great for this kind of experience, but it has one big problem: abysmal refresh rate. Enough for books, irrelevant for price tags so this is where it succeeds. Movies or fast typing? No.

I heard a rumor that an eink display can be oveclocked to reach reasonable rates, but it would probably wear it down rather fast.

I'm not sure if this would accomplish what you're looking for, but it did give me an idea: wouldn't it be cool if they had a monitor that used the fake ink effect (that thing that non-backlit digital books sometimes use) to make displays look "more natural" (read: different in an interesting way)

I think that'd be cool at the very least, and, due to it not being backlit, it would possibly get rid of the blue light issue (i'm not an expert in this field so idk how much of an issue blue light actually is when it comes to dopamine overdrive)

I might try and make a monitor like this if I can gather the skills to do it, I am only getting more excited about this idea lol

Ty for the inspiration!

Hyprland has a way to write custom shaders which would do what you want https://github.com/hyprwm/Hyprland/issues/1140#issuecomment-1546245134

This is not a thing because that's not a concern for developers. They make the software in whatever way they think it looks best, maybe add some accessibility options, and leave the fine-tuning to the user's display options. It's strange to me that you interpret this as an ideology issue for developers.

Windows 11 has a color filter setting with hotkey.

Win + Ctrl + C but you'll need to enable it and select grayscale first.
