What happened is that Photoshop assumed I knew what I doing (not always the best assumption to make) and, rather than tossing up an error message complaining that I can't delete pixels on a Background layer, it automatically converted the Background layer into a regular layer, which it named "Layer 0". How, then, did I manage to erase the pixels? Is there some sort of "Extra Strength" setting for the Background Eraser that we haven't looked at yet? One of the things we can't do is erase pixels on them, since transparency is not allowed on a Background layer (after all, it's the background, and not being able to see through it is part of what makes it a background). Photoshop treats Background layers differently from normal layers, with different rules for what we can and can't do with them. A moment ago, we saw that my image was sitting on the Background layer. That's Photoshop's way of representing transparency on a layer, which, if you're familiar with Photoshop, may have you wondering what's going on here.
Notice the checkerboard pattern that appears in place of the areas I've erased. If you need to undo multiple steps, press Ctrl+Alt+Z (Win) / Command+Option+Z (Mac) repeatedly. If you make a mistake like this, simply press Ctrl+Z (Win) / Command+Z (Mac) on your keyboard to undo it. Moving the crosshair over a new color causes Photoshop to change the color it's erasing. To select it, right-click (Win) / Control-click (Mac) on the Eraser Tool, and then choose the Background Eraser Tool from the fly-out menu that appears:
