Problem

Matplotlib currently offers a limited selection of built-in styles. Most feature light-toned backgrounds (white or gray), and there is only a single dark theme (dark_background).

This restricts users’ ability to quickly apply aesthetically pleasing and context-appropriate visuals, especially for dark-mode environments.

Proposed solution

Introduce a broader suite of ready-to-use styles—including multiple dark themes and visually diverse light options—that are curated by someone with strong design and colour-scheme expertise. This would empower users to easily switch between visually rich styles for presentations, publications, or dark-mode workflows.
Suggested enhancements:

• Add a few dark-mode themes with distinct colour palettes beyond dark_background, featuring complementary accent colours and improved contrast.
• Introduce several light-mode styles with diverse hues, backgrounds, and typography.
• Ensure new styles integrate seamlessly into the existing plt.style.use(...) interface and are well-documented in the style reference gallery.
