Photoshop is a powerful image editor that you can use to change the background color of your images. To do this, you need to first open Photoshop and then click on the Edit button. Then, select the Background tab and click on the Change Background Color button. In the resulting window, you will need to provide a new color name for your background. For example, if you want your background to be blue, then type in Blue into the text field and click on OK. Once you have provided a new color name for your background, click on the OK button to close Photoshop.
