Change Theme Color

[GoldLion123RP]

From: Release notes for 1.8b 🎉 of February 21, 2025 - update I can no longer change theme color to transparent or 0, which automatically helps me to adapt my desktop background color in nice blur effect. Take a look at the Screenshot provided taskbar's background.
Bring it back. It really enhanced the overall look and experience.

Try zen.theme.gradient.show-custom-colors to true, you'll get custom colors back.
But be careful because of #5777. I myself has downgraded back to use 1.7.6b instead.
