Which tool is typically used to change colors in an image?

The Sponge/Color tool is specifically designed for altering the color saturation and vibrancy within different areas of an image. When you use this tool, it allows for selective adjustments, meaning you can enhance or mute colors in certain parts of the image without affecting the overall color scheme. This can be particularly useful for artistic effects or to bring attention to specific elements in the artwork.

In contrast, while the Paint Bucket tool fills areas with a solid color, it does not provide the nuanced adjustments that the Sponge tool does. The Gradient Tool is used for creating transitions between multiple colors and is not primarily for changing existing colors. The Select Tool, on the other hand, is meant for selecting areas of an image for various purposes, but it does not modify colors by itself. Thus, the Sponge/Color tool stands out as the most appropriate choice for changing colors in an image.
