+ * Color tint management module implementing HSL-based color manipulation.
+ * 
+ * Implements color tinting using HSL color space transformation with circular interpolation.
+ * Features noise reduction and smooth blending for high-quality results.
+ * 
+ * Implements the following design patterns:
+ * - Observer Pattern: state management and effect application
+ * - Factory Pattern: UI initialization
+ * - Strategy Pattern: color manipulation algorithms
+ * - Command Pattern: state reset operations
+ * 
+ * Color manipulation process:
+ * 1. Convert RGB to HSL color space
+ * 2. Apply circular interpolation for hue blending
+ * 3. Smooth blending for saturation and lightness
+ * 4. Noise reduction through value rounding
+ * 5. Convert back to RGB color space
+ * 
+ * Features:
+ * - Circular interpolation for natural hue transitions
+ * - Noise reduction through value rounding
+ * - Smooth blending with quadratic easing
+ * - HSL color space for better color manipulation
