Change Background Colors
You and can change the background colors for a design by going to My Images > Backgrounds.
The background for a design will be set to "Transparent" by default. This means that PNG downloads will download with a transparent background. All other options (JPG, PDF) will be flattened to a white background. To change the background color to a different color, uncheck the Transparent Background option. Then you can use the color picker and color box below to select a color for the design background color.
