Colorify text in Qubes' global clipboard
Before using this script, you need to create a named disposable sys-colorify, which will do the actual processing. This way, dom0 is entirely isolated from any potentially-malicious inputs
sys-colorify can be based on any template, including minimal templates. It is recommended to deny network access, since it really has no need to connect to the internet
To install, copy color.py into /usr/local/bin, then mark it as executable with sudo chmod +x /usr/local/bin/color.py
Once you have done this, you should be able to use the script by running color.py <color>
Optionally, you can bind color.py to a keybind in dom0
The Qubes official documentation has information about copying files to dom0: https://www.qubes-os.org/doc/how-to-copy-from-dom0/#copying-to-dom0
For better security, you should download this into a disposable VM, to prevent a compromised qube from tampering with the data locally
For the best security, you should use qubes-clean to copy this script into dom0
