Bucket The Paint Bucket fills a continuous similar colour area with the foreground colour. It is bound to the K key. Secondly, it will allow you set the glue and transparency for the paint. Please see the layers section of the page for more information about glue and transparency. Command temporarily actives the path arrow.
Option temporarily actives the eyedropper.
The bucket dates back to the days of MacPaint, and for the most part still functions the same way. In other words, the paint bucket really seldom works like you want it. It is useful for flat tone areas, but confronted with anti-aliasing, it becomes pretty confused, even with lots of tolerance adjusting.
