Add new colors to constants.py

Add new hue to colorize.py

Add the new color name to the lists in update-variations.py

Run the Python script update-variations.py for the new color (e.g. ./update-variations.py Red). This will generate new assets in src/Mint-Y/variations/.

Manually create a new directory for the new theme in files/usr/share/themes. It's best to copy an existing one as a template.

In there:

• Adapt the theme name in index.theme.
• Create new thumbnail.png images.

Run the Python script generate-themes.py. This will create the themes in the local directory usr/share/themes.

Test the themes by copying them to ~/.themes and applying them.

In Git commit and push all newly created files to a new branch.
