Theme Park on One UI 7 Adds Unwanted Green Color to Custom Palettes

[Bastet999]

Hi everyone,

I’ve been running into a strange issue with Theme Park on One UI 7 and wanted to see if anyone else has experienced this—or found a fix.

Whenever I create a custom theme using Theme Park, everything looks fine during setup. I manually customize every color in the palette. But once I apply the theme, some UI elements (like toggles, highlights, or buttons) show up in green—even though I never selected green anywhere in my palette.

When I go to Wallpapers and Style > Color Palette, I notice that my custom palette includes an extra green swatch at the bottom. It seems like One UI 7 is injecting a sixth color into the palette that Theme Park doesn’t let me customize. This green tone appears to be Samsung’s default fallback when a color slot isn’t defined.

Interestingly, if I use the Color Palette feature directly from Wallpapers and Style (without Theme Park), the colors apply correctly and no green shows up.

Here’s what I’ve tried:

- Rebuilding the theme from scratch in Theme Park

- Manually customizing every visible color slot

Still, the green persists.

Is this a known limitation with Theme Park on One UI 7? Is there a workaround to override or remove that sixth color slot? Would love to hear if others are seeing the same thing—or if Samsung is planning a fix in future updates.

Thanks in advance!

Hi @Bastet999, 

thank you for your feedback. 

It is possible that the app Theme Park still needs some updates in order to be optimized and work properly with One UI 7. 
At the moment I advise you to create your custom themes using Wallpaper and Style (without Theme Park, as you already did) and to stay tuned in order not to lose any Theme Park update. 

I remain available in case you need something else.

Have a nice day ☺️✨
