In this tutorial I will show you how to change a background color in a Photoshop document. This was a request by Jim Juris...
1. Open a NEW document. It will appear on your layers palette as "Background". You can see it highlighted there in your layers palette on the right.
2. Create a new layer by clicking on the "New Layer" button at the bottom of your layers palette.
3. You will see the "New Layer" you just created in your layers palette now.
4. In this example I have added a paintbrush image to the document on the new layer. I simply chose the brush I wanted to use and put in on the new layer. Make sure the new layer is highlighted in the layers palette, or it will end up on your background layer.
5. Now choose or highlight the Background layer by clicking on it in the layers palette.
6. Now go to the "Edit" menu and choose "Fill" from the dropdown menu.
7. In this example I have chosen a red for my color which appears in the "foreground" on the toolbar to the left. (Note the red box that is circled). A menu appears once you have chosen "Fill" from the "Edit" menu. Depending on what colors you have on your tool bar, you can choose to fill the background with the foreground or background color.
8. Once you click OK the background color will change to your choice.
Because you added your paintbrush to a new layer, filling the background will effect only the background layer.
There you have it. Please let me know if I need to make any further clarifications. Have fun with Photoshop every day!!
