Adobe Photoshop/Paint Bucket Tool

This tool is another of the most commonly used tools in both rendering and photo editing. It fills the selected area with a color and is often used to create a background. It is also one of the more straight-forward tools in Photoshop, and is relatively simple to use in most cases.

The Tool
Start by clicking the paint bucket icon. It will automatically use your current foreground color. Then goto the top of the page and find "tolerance". This works the same way as it does with the magic wand tool. Click where you want to fill with the color and it will automatically fill the selected area with your color. (It will fill like this: . . a. ) It is a very basic, but useful tool. But sometimes you will want a gradient, for that use the Gradient Tool
