Improve RGB Color Picker Functionality

[Amansingh0807]

The current RGB color picker lacks real-time value display, optimized event handling, and proper default values. It also doesn’t provide clear feedback to users about the RGB values they’re selecting.

Enhancements Needed:

• Add real-time RGB value display beside sliders.
• Set default slider values to prevent undefined behavior on page load.
• Optimize event listeners using a loop for cleaner code.
• Improve UI feedback for a better user experience.

Expected Outcome:

• Dynamic RGB value display.
• Smooth real-time color updates.
• Clean, maintainable code with optimized event handling.
