What if it's white on black?

it should be light grey on dark grey background. and then you simply get a monitor with higher brightness and contrast. the dynamic range of a monitor is there for images, not text. text is NOT supposed to use the whole dynamic range of the screen. it's the same as how dynamic range of speakers is for music, not speech. you don't blast an audiobook at 100 decibels. page design isn't supposed to make text pretty. it's supposed to make pictures pretty without making you blind.

I don't think there is a logic relationship between your sentences, but I will just follow what you're saying. But what happens if users don't have a monitor with higher brightness and contrast? How many people in the world have such a monitor?

quantity over quality. not everybody matters.

IOW why do you care about the experience of a person who doesn't care about his own experience ? if they don't have a good monitor it means they don't care how things look. worry about people who care enough to upgrade their monitor. i make more comments on this subject than a million people with dim monitors combined. they are irrelevant. you

if their monitor is so dim and pale that they can't read the text it will be a good clue for them to get a new one.

You could add the user avatar, have a nice font, have some whitespace, add some other metadata, etc. Something like this:

The fact that multiple "beautiful twitter screenshot" tools exist should tell us something...

stop worrying about freeloaders. if somebody uses a monitor they found on the garbage they don't deserve to see anything. most people are beyond help. stop trying to help them.

Most people are on phones, not monitors

phones have incredible brightness and contrast when used indoors. a separate mode is in order for outdoor use.

Why not both 🤷🏻‍♂️

So your solution is to change people to fit your ideal society, like Karl Marx?

Karl Marx is winning - isn't he ? we are supposed to advance technology not retard it. jokes aside the right way to do it is to have controls as follows: 1 - choose screen type - edge lit / FALD / miniled / OLED 2 - choose ambient brightness level - sunlight / daylight / office lighting / residential light / dim room / complete darkness 3 - HDR - yes / no 3 - vision acuity - normal / astigmatism etc. my grandma for example didn't like dark mode but she was almost blind. i let her have bright mode even though i found it revolting myself. i think people with astigmatism can't use dark mode for example.

I'll settle for a compromise.

I have astigmatism and use dark mode, never considered that fact
