Raspberry Pi Asked by charliesneath on October 5, 2021
I am using Emacs on my Raspberry Pi (an RPi Zero W and RPi 4) through an SSH connection with the Blink terminal program on my iPad.
Emacs seems to be limited to 256 colors, but the themes I am using (Dracula is one of them) support 24-bit color. The colors render correctly when using Emacs locally on my MacBook.
Is it possible to use Emacs with 24-bit color when connection to the Raspberry Pi over SSH?
Please let me know if there is any additional information I can provide to help clarify. Thank you!
I was able to get this working. After following the instructions from the Emacs FAQ, I found that I had to run export TERM=xterm-24bits (note the plural ‘bits’) and that enabled 24-bit color when running $ emacs.
If anyone is interested in getting 24-bit color to work over Mosh, you’ll need to build from scratch as described here.

I'm not familiar with "Blink" but presume this is not a limitation of that.
After logging in and before you start emacs try:
export TERM=xterm-256color
export COLORTERM=truecolor
The first one is necessary for the second one to work, which should set 24-bit (aka "true color") depth if possible.
I'm not an emacs user either; if this does not work check if the version on the Pi was compiled to use true color in terminal mode. Related to this point, I am an mc user, which can be compiled to support true color and usually is. Unfortunately, the version used in Raspbian/RpiOS (actually, I think Debian derived systems generally) uses an alternate TUI library (slang instead of ncurses) which only implements 256 colors.
