Which tool would you use to fill a contiguous region with color quickly?

• A. Paint Bucket Tool
• B. Lasso Tool
• C. Gradient Tool
• D. Quick Selection Tool

Answer: (A)

Filling a contiguous region with color quickly relies on a tool that paints all connected pixels that are similar in color with a single click. The Paint Bucket Tool does exactly that: set your foreground color, click inside a region that is connected and shares similar color values, and the entire area fills with that color. You can adjust the tolerance to include more or fewer nearby colors, which helps when edges aren’t perfectly uniform. This makes it ideal for solid-color shapes or areas that are one consistent hue. If you need a gradient or you have noncontinuous areas, other tools are better suited. The Lasso Tool is for drawing or selecting freehand shapes, the Quick Selection Tool helps you pick areas by edges to edit, and the Gradient Tool creates a color transition rather than a solid fill.
