I have a large area of a single color I need to remove from an image.
Is it possible to use the Paint Bucket tool as an eraser type tool? Can I click on an area of a particular color and the color is simply removed and no color is substituted?
It's easy to use the Magic Wand (color selection tool), with Alpha Channel enabled.
That's right, you can just press the delete key after you select it with the Wand tool and it will erase the content in the layer.
