Problem Description

The current Accent Colors menu is cluttered with a mix of colors derived from various themes, default options, etc., totaling about 45 colors.
This lack of organization makes it difficult for users to quickly find and select their desired color, and can even make them feel overwhelmed.

Proposed Solution

To enhance user experience, I thought of the following organizational changes to the Accent Colors menu:

1. Theme-Specific Colors:
   Display only colors that are relevant to the user's currently selected theme. This reduces visual clutter and makes selection more intuitive.

2. Thematic Organization:
   Group colors by theme (e.g., Solarized, Catpuccin, etc.). Users would first select a theme, which would then reveal the associated colors. This hierarchical structure allows for easier navigation and selection.

Alternatives Considered

• Color Palette Preview: Instead of a list, maybe a visual grid of colors for would make the selection easier. However, this may still suffer from clutter if all colors are displayed without organization.
• Organized via contrast As mentioned in [Feature Request]: Mark & sort color themes by color contrast with base theme #3934 this would also be a great option, but not reduce the clutter in my opinion. It would still be a mess of colors, now being sorted by contrast.
