Colorizer VS vCoolor.vim

Not sure how to force programs to output colors, that's generally program-specific. You can use Colorizer to highlight ASCII escape sequences once you get color output though.

Colorizer has functionality for things like this. Not sure if it supports Hex, but it does support to translate between RGB and Terminal colors.

I made my own plugin: https://github.com/chrisbra/Colorizer/

Never mind. I didn't google hard enough. https://github.com/chrisbra/colorizer does the job. Once installed, type :ColorToggle to activate it in any file.

Not for GVim, which could call native GUI widgets. I found this old-ish plugin that actually can call color pickers form terminal by invoking them in command line. A little hacky, but works. https://github.com/KabbAmine/vCoolor.vim/

I used to use this other color picker plugin back in the day before I pruned a bunch of plugins: https://github.com/KabbAmine/vCoolor.vim

An awesome related plugin is vCoolor which lets you pop up a GUI color picker for the color under the cursor.

I like yad[0] for this. For example, I use it to present a GUI color picker to change/insert colors in Vim (via a plugin called vCoolor[1]). I also use it in some i3/sway scripts that need user input or to show a progress bar.

And as bonus, I use this https://github.com/KabbAmine/vCoolor.vim to trigger external color code picker when (tbh rarely) I need that.

Checkout the vCoolor.vim plugin. It allows you to insert a new color or change existing colors in code. It opens a pop-up window (outside of the TUI) were you can see the chosen color room and select a color as you are probably used to.
