UI Improvement: Enhance interface with lighter color scheme

## Issue Description

The current UI appears quite basic and could benefit from a visual enhancement. I think implementing a lighter color scheme would significantly improve the user experience and make the interface more modern and appealing.

Suggested Improvements

- Use lighter, more vibrant colors for the overall theme
- Consider implementing a softer color palette that's easier on the eyes
- Add more visual contrast with lighter backgrounds and appropriate accent colors
- Improve the overall aesthetic to make the interface more engaging

Benefits

- Better user experience
- More modern and professional appearance
- Improved accessibility and readability
- Enhanced visual appeal

I'd be happy to contribute to this improvement if needed.
