Different colors for editor vs other elements for better visual distinction

First, thank you for the Rose Pine theme—it’s visually stunning and a pleasure to use. However, I would like to highlight an accessibility issue with the current VS Code implementation

Accessibility Issue:

The current color scheme uses the same shade across the sidebar, other panes, and the editor area. While this creates a cohesive and aesthetically pleasing look, it can make it challenging to intuitively distinguish between different sections of the editor, especially during prolonged usage. This lack of visual distinction can be an accessibility issue for many users, particularly those with visual processing difficulties. Even for those without particular visual accessibility issues, this increases cognitive load, which can impact focus

Suggestion:

• Introduce slightly different background colors for the sidebar, other panes (such as the file explorer, top pane, etc.), and the main editor area.
• The differentiation doesn’t need to be drastic—subtle variations would be sufficient to provide a clear visual distinction between these sections.

Start by inspecting the VS Code theme color definitions that control the sidebar, other panes, and editor background. Compare the current colors in VS Code and introduce subtle distinctions that improve section boundaries without disrupting the Rose Pine appearance; visually verify the result across those areas.
