How does a color picker work in digital coloring?

A color picker in digital coloring apps allows users to select precise colors for their artwork. It typically presents a full spectrum of colors, often in a wheel or grid format. Users can tap on a specific color to select it, or use sliders to adjust hue, saturation, and brightness for more refined color selection. Many color pickers also display recently used colors for quick access. Some advanced apps allow users to input specific RGB or HEX color codes. Additionally, many color pickers include an eyedropper tool, enabling users to sample colors directly from their artwork or even from imported images.
