Which tool fills adjacent pixels similar in color value to the pixels you click?

Which tool fills adjacent pixels similar in color value to the pixels you click?

• A. Gradient Tool
• B. Paint Bucket Tool
• C. Lasso Tool
• D. Marquee Tool

Answer: (B)

Filling areas by color similarity and connectedness is what the Paint Bucket Tool does. It samples the color at the pixel you click and fills all adjacent pixels whose color is within a chosen tolerance. Because it works on a contiguous region, only nearby pixels that match that color range get painted, making the fill look like a blob that follows the actual color boundaries. The Gradient Tool creates a smooth transition between colors across an area, not a single connected patch based on similarity. The Lasso Tool is used to draw freeform selections, and the Marquee Tool makes rectangular or elliptical selections—neither of which fills by color similarity automatically.
