For the example below, I selected the inverse of the previous selection used above. The inverse selected all the white pixels surrounding the previous selection. Next, I choose an orange foreground color. Then I click on the white area of the image to fill the white with the orange foreground color. The options I choose are also shown.
Background color makes gradient fills and fills in the erased areas of an image.
By default, the foreground color is black and the background color is white. Changing the Foreground Color Click the top color selection box located in the Toolbox. Choose a color from the color picker dialog box that appears by clicking anywhere in the rainbow colored bar with the mouse to select the general color and clicking anywhere in that color's box containing more specific colors. Click on the Eyedropper Tool Hold down the ALT key on the keyboard.
