How to change background color in an image with a single layer?

I need to change the background color of a PNG image that has only one layer, using PhotoShop 2018. You can't select everything else and mask it because it's a very complex image, and the Spot Healing Brush tool doesn't seem help much because the color I'm trying to change is very subtle and only appears in certain areas.

 

There must be an easy way to just change the entire background color, but I have yet to find it.

 

Can anyone help?

Another option is the Filter > Camera Raw Filter.

 

Here I have set the white balance to the buff background using the eyedropper (Basic) and have also applied Vignette reduction (Optics).

 

Again, just a start point, more subtle and finessed results are of course possible.

Hmm… I don't see a Camera Raw filter in the Filter menu for Photoshop CC 2018.

@The Instigator 

 

Despite the simplistic appearance of the image, as you have found, it isn't a 1 click edit.

 

I would like to offer the following as another approach for you to explore.

 

I have set color sampler tool markers in the upper left and lower right and I am using the info panel to evaluate when white is achieved.

 

More work would be required, this is just a very fast start point which gets you 95% there in less than a minute.

 

Here is an animated screenshot GIF, it only uses two adjustment layers (selective color and levels):

    It looks very nice, but as I said before, I rarely use Photoshop for anything. If you had a step-by-step tutorial of how to do this (and eliminate the vignetting for all white background), that would be really helpful. Or, if there's one online that deals with this type of image, that might be helpful as well.

    I appreciate that you rarely use Photoshop.

     

    The GIF animation is the step-by-step, there are only two steps and the values are highlighted in the adjustment layers properties panel. You can download and open up the GIF animation in Photoshop if it is looping too fast in each frame, or take a screenshot of each frame etc.

     

    Search up how to add an adjustment layer if you don't know how.

     

    As for the vignetting, you could simply add a new layer and paint white with a brush, or use the Dodge tool set to affect the highlights which may be better as it would help protect the signature on the lower right.

    Images that are difficult to do instantly, for people who are not used to or familiar with selection using the color range or via the RGB channel, if you don't understand it, I suggest you learn to select using the color range or RGB channel, because images like that, can only be done with those 2 methods, the method is not too perfect, because a white edge will appear, or parts that are not perfectly selected.

    for reference, you can see this tutorial

      That's a much less complex image than what I posted, so it would be impractical for me to attempt, and probably anyone else, too.

      Are you trying to change the tan color? Go to the Select drop down menu - choose select color range and select the color you want to change. Use a hue saturation adjustment layer to make the change. This is just one option. It's not an easy task because there are shadows and gradients in there.

      I'm trying to change the background color. It should be a pure white, but it's obviously not, and that's why I want to change it to that.

      By @The Instigator

       

      I tried to remove the background using various advanced methods, and after a while I started to think about why they aren’t working when they usually do. And that led me to looking at the reasoning you posted. Looking at the image, it does not look like the background is supposed to be pure white.

       

      One reason is the way the edge shading integrates into that background. The other reason is that if the background is truly supposed to be white, but it is showing up off white, then color balancing the background to neutral should make it white. And that works, it turns pure white like you want, but it also makes all of the other colors in the image look wrong.

       

      So I concluded that the background is not supposed to be white, that the warm background color is probably an integral part of the artwork as intended by the artist.

       

      If this is an image where the background is not really intended to be removed, then the usual and more intuitive software features for background removal are less likely to work easily. If you want to remove a background that’s not really a background, we can’t tell you not to, but because it looks like it’s actually part of the actual art, to remove it probably requires manually separating it from the details of the art by hand, using some combination of the manual techniques already shown.
