Benefits of Dark/Light Themes

Dark and light themes have been a topic of discussion among developers and designers for a while now. The benefits of these themes are numerous, and they can be categorized into several areas:

Visual Comfort

Customization

Personalization: Dark and light themes allow users to personalize their experience, making it more enjoyable and engaging.
Accessibility: Customizable themes can also improve accessibility for users with visual impairments.

Performance

Battery Life: Dark themes can help reduce battery consumption on mobile devices, as they require less power to display.
