Step 1: Open your file in Photoshop
The first step is to open your image in Photoshop. To do so, simply click on File, then click on Open, and select the image you want to edit.
Step 2: Create a new layer
Next, create a new layer by clicking on the Layer menu, then selecting New Layer. You can also use the shortcut Ctrl + Shift + N (Windows) or Command + Shift + N (Mac).
Step 3: Choose a new background color
Now it’s time to choose a new background color. You can do this by selecting the Paint Bucket Tool (G) from the toolbar, then selecting the color you want to use from the color swatches on the left.
Step 4: Paint the new layer
With your new layer still selected, use the Paint Bucket Tool to fill the layer with the new color. If you find that the background color is not covering the entire image, you can use the wand tool to select the areas that need to be colored in.
Step 5: Adjust layer settings
The next step is to adjust the layer settings to ensure the new background color remains only in the background. To do this, select the layer you just created, then click on the Lock Transparent Pixels button at the top of the layer panel. This will ensure that the new color will only be applied to the blank pixels on the layer.
Step 6: Refine the edges
If you have areas where you want to keep the original background color, you can refine the edges of the new layer. Select the layer, then click on Layer Mask at the bottom of the Layers panel. From there, choose the Brush Tool (B) and use a white brush to paint over the areas where you want to reveal the original background color. You can adjust the opacity of the brush to achieve a more natural transition between the two colors.
Step 7: Save your file
Once you are satisfied with the new background color, save your file. Go to File, then Save As, and choose the file format you want to use. It’s a good idea to save your file under a new name, so you don’t accidentally overwrite the original image.
In conclusion, changing the background color in Photoshop is a simple process that can be used to achieve a variety of effects. By following the steps outlined above, you can create a new layer, choose a new background color, refine the edges, and then save your file. With practice, this process will become second nature, helping you to quickly and easily change the background color in any image you work on.
