We need to create a submenu that allows users to set a custom color scheme for Reader View. There should be options for choosing the text and background color. We are also considering options for modifying the color of links and text highlight in narration mode. Additionally, the menu should include a toggle for 'Use system colors'. 

**Open question**: Is it necessary to allow the user to modify link colors? Link colors are different for light/dark mode, but we could detect color brightness from rgb values and set it automatically. 

Same consideration goes for Listen text highlight. We don’t want to clutter the menu with too many options, but if we set things automatically it would need to be able to handle any color.

We need to create a new menu that allows users to set a custom color scheme for Reader View. There should be options for choosing the text, background color, links, and listen text highlight. The menu also needs to display the existing preset color theme options.
