Click File in the top-left corner of the Paint window. Click Open in the drop-down menu. Go to the location of the image you want to open. Click the image. Click Open. If you aren’t opening an existing file, create the Paint project you want to use before proceeding.

You can zoom in to get a better view of the color by clicking + in the bottom-right corner of the window.

Skip this step if the color you want to replace the first color with isn’t on the canvas.

If you skipped the last step, you’ll instead click the Color 2 box at the top of the page and then click the color you want to use from the palette at the top of the window.

Do not use the left mouse button for this step. Doing so will cause the eraser tool to erase anything you drag it across instead of just erasing the color you selected as the one to replace.
