Which panel is used to adjust the color of an object in Illustrator?

The Color panel in Adobe Illustrator is specifically designed for adjusting the color of objects. It provides a variety of options for selecting colors, including RGB, CMYK, and HSL sliders, as well as the ability to adjust the color’s opacity. This panel allows users to customize colors in a straightforward way, making it easy to achieve the desired hue, saturation, and brightness for any selected object.

While the Swatches panel contains predefined colors and patterns for quick access, it does not offer the same level of customization for adjusting specific color values. The Styles panel focuses on applying and managing graphic styles, which encompass multiple settings beyond just color, such as effects and strokes. The Appearance panel provides a comprehensive view of all the visual attributes of an object, including fill color, stroke color, and effects, but it is not primarily used for adjusting color alone; rather, it serves to manage various appearance properties collectively.
