Smart Erasing in Paint

Is there an element of your Paint drawing you'd like to erase, without affecting the rest of your work? Before you move the Eraser tool around your drawing elements, remember that Eraser tool will selectively erase (or replace) a single color. Drag the tool over any part of the canvas, and everything but the selected color remains untouched.

First, click the color you'd like to erase (or replace). Then, right-click the color you'd like to replace it with (usually the background color). Select the Eraser/Color Eraser tool, then hold down the right-mouse button as you drag the mouse pointer over the color you're trying to erase or replace. Only the selected color disappears!
