Getting the current Framebuffer color mapping from CLI

[andyngo]

Hi, is there an option to return the current Framebuffer color using the CLI?

For example, I'm trying to create a bash command to set Standard Framebuffer or Grayscale Framebuffer conditionally depending on the currently set Framebuffer color mapping.

AFAIK, these commands are only accessible through the perform operation. Is there a way to use the 'get' operation to return the color mapping?

Thank you very much in advance.

Unfortunately you can't easily read these settings. The related (undocumented) calls don't work reliably according to my tests.

Thank you for your reply. I'll just set it up as 2 different bash scripts and run them using Raycast manually. Not a big deal, thanks again for such an incredibly useful software!

Probably slightly off-topic, but is there a way to adjust the color temperature if Grayscale Framebuffer is enabled? I'm trying to create my own "Reading Mode" preset based off this and would love to have a warmer display even when Grayscale is enabled.

Sadly no, even Night Shift does not have an effect on external displays (it does on the internal as that is working differently), this method of grayscaling the framebuffer is super low-level and supersedes everything.

(of course for external displays if it supports DDC color changes, you can simply use DDC to make things look warm).

Thank you for the prompt response! Unfortunately I'm using a rather old and obscure monitor which does not have any DDC/CI feature. Good news is I can still quickly switch between different different colour presets using the OSD on the monitor.
