Linux desktop theme customization is limited to preset color schemes, forcing users to accept unwanted aesthetic choices

Linux users who adopt GTK themes like Layan are locked into fixed accent color options (e.g., purple) that don't match their personal preferences or workflow aesthetics. They cannot easily customize the theme's core visual elements without forking the project or manually editing code, creating friction between wanting a polished theme and needing visual control. Current solutions require either accepting the default colors or abandoning the theme entirely.
