Change Background Color in Photoshop (Clean, Flexible Method)
This tutorial shows a flexible, non-destructive way to change a photo’s background color in Photoshop. You’ll precisely select your subject, use a group mask to target only the background, recolor it with Hue/Saturation, and control brightness with Levels. You’ll also learn a clean blur method that avoids edge ghosting.

Step-by-step instructions
Select the subject accurately
Go to Select → Subject to create an initial selection.
Press Z to zoom in and choose the Quick Selection Tool.
Hold Alt (Windows) or Option (Mac) and brush to subtract unwanted areas.
Press Q for Quick Mask; paint with the Brush Tool—white to reveal, black to conceal; use Shift-click for straight lines; press X to swap colors. Press Q again to exit Quick Mask and double-click the Hand Tool to fit the image.
Mask a group to affect only the background
Create a new Group in the Layers panel.
With the selection active, click Add Layer Mask to apply the selection to the group.
Select the group mask and, in the Properties panel, click Invert so the mask targets the background (background appears white on the mask).
Recolor the background with Hue/Saturation
Inside the group, click Create new fill or adjustment layer → Hue/Saturation.
In Properties, check Colorize.
Adjust Hue to pick a color and Saturation for intensity.
Avoid using Lightness here to preserve detail.
Control background brightness with Levels
Create a Levels adjustment layer below the Hue/Saturation layer.
Press Ctrl + [ (Windows) or Command + [ (Mac) to move the Levels layer down if needed.
Adjust the midpoint (gamma) and black/white sliders to fine-tune brightness and contrast of the background.
Blur the background without ghosting
Duplicate the Background layer (Ctrl + J on Windows, Command + J on Mac).
Move the duplicate into the group (Ctrl + ] on Windows, Command + ] on Mac) so it’s constrained by the background mask.
Go to Filter → Blur → Surface Blur, adjust Radius/Threshold as needed, and click OK.
Avoid Filter → Blur → Gaussian Blur, which can cause edge ghosting around the subject.
