2. Artistic Effects: Adjusting hue can create visually striking effects, adding a creative touch to your sliders.
3. Focus and Highlight: Allows you to highlight specific areas or features by altering their color tone.
4. Improved User Engagement: Offers an interactive way for users to explore changes and transformations with a unique visual approach.
