Is there a way to shift the screen color hues with colors inverted?

de flag

I've managed to invert the screen with xcalib -alter -invert, but now blue is orange etc.

Isn't there a way to hue-shift the screen colors as well, so only the brightness is inverted and not the hue?

(side note: I figured out I can run OBS with a color correction filter to see my first monitor the way I want. It is a bit hacky though!)

Are you talking about a **text screen or graphical desktop environment** with application windows, for example `gnome-terminal` or `xterm`. Can you use ANSI sequences?

Did you try with the same `xcalib` command and replace `-invert` with '-brightness` (short `-b`) according to 'man xcalib` at the internet (I have not installed this tool) or some other combination of options? An alternative might be to select another theme for the desktop (switch between a light and a dark theme). Maybe this link will help you: [Automatic Light / Dark Mode?](https://askubuntu.com/questions/1234742/automatic-light-dark-mode)

Yeah normally I do `xcalib -alter -co 50` once or twice to dim the screen, but it would be even more convenient if I could replace white with black for text without turning people blue in images / videos

'replace white with black for text': Do you mean subtitles or text in a terminal window?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
