Trying to adjust yellow saturation from images to match another image

Hello everyone,

 

Foremost, I am a complete novice when working with Photoshop. I have been searching in google to figure out how to change or remove yellow oversaturation from an entire image to make it comparable to, or the exact same, color scheme from an image that does not have the same oversaturated yellow effect.

 

A little background, I work in research, I have images of tissues from 3 different phones. One of those phones causes a yellow tint on all the images that is unnatural, it creates good images but due to the blue background, it causes the image and tissue to look unnaturally yellow compared to the others.

 

I've tried using hue tool, looked at RGB color palates, saturation/desaturation tools, but have been unable to match the color profile of the more natural image to modify the image with the yellow tint. I am attaching two images that I am working with. Does anyone have suggestions on how to correct this?

 

Sincerely appreciative!

My suggestion is to color correct with the info pallet set for Lab reading not RGB. Hue/Sat may be the best tool to try after a good selection as the subject may need a different correction than the background.


How does this look (I'm hoping I matched the color you wanted, not sure):

 

It was actually a lot easier than I suspected:

1. Use Select Subject (Under select menu). Did a good job of selecting the tissue. 

2. Use the Match Color command (Adjust). Make sure you target the image you want to match, you'll see this in the preview update. 

3. Inverse the selection (you only want the bkgnd). This is done in Select Menu. 

4. Use Match Color Again. 

Pretty close, the bkgnd seemd like it needed a tad magenta so I used Hue/Sat command and moved the hue to the right a tiny bit. You can play more and get closer, but this was done in about 3 minutes.

Are the color spaces the same?

Are you viewing Lab values and adjusting based on those numbers (ideally)?

    Correct, the blue spacing is the same object being used as a backdrop for all the imaging, including the ones provided. The top image is representative of the true color of the backdrop. Hopefully that answers the question, I'm not entirely sure what you mean by Lab values otherwise. 

     

    Thank you for your quick response!
