Which tool allows you to modify specific colors in an image?

The Color Picker is a tool that enables you to select and modify specific colors in an image effectively. This tool allows users to sample any color present in the image and make adjustments, which can include changing the hue, saturation, brightness, or replacing it entirely. By using the Color Picker, an artist can ensure that modifications maintain the desired aesthetic and color harmony throughout the image.

In contrast, the Lasso tool is primarily used for selecting irregular areas of an image, whereas the Clone Stamp tool duplicates parts of an image to another area. The Brush Tool allows for painting or applying colors onto the canvas, but it does not specifically target and modify existing colors. Thus, for directly changing specific colors in an image, the Color Picker is the most suitable choice.
