[Feature] Better dark theme

[Kruegerrr]

While the dark theme is a valuable feature, it currently suffers from poor readability due to insufficient color contrast. The current color scheme utilizes #1e1e1e for the background and #bbbbbb for text, resulting in a contrast ratio of 8.68:1. According to Material Design 2 guidelines, dark surfaces and 100% white body text should have a contrast level of at least 15.8:1 for optimal readability.

Please modify the dark color scheme to follow these contrast guidelines. This should be a simple improvement that can significantly enhance the readability and usability of the dark theme, hence provide a more comfortable experience for users who prefer this mode.

Furthermore, I would like to suggest the introduction of additional color themes, similar to those available in modern code editors. Offering a range of color themes would allow users to personalize their experience and cater to a variety of preferences. This feature would not only enhance the visual appeal of the platform but also provide users with the flexibility to choose a color scheme that best suits their individual needs and preferences.
