If you have photoshop a fast way is to go to Levels or Curves and select the white eye dropper in the bottom right of the dialog box. Double click on the eye dropper and change the RGB values to 235, 235, 235. Then click on the white shirt on that side of the person and the color cast should go away. I teach various other methods in my Photographer's Toolbox for Photoshop #1 class

Fix #1 - Turn it into a Black and White. Fix #2 - Warm the whole print. Fix #3 - Desaturate the colors.

Thanks Lewis and Chris for your ideas. I tried Lewis's idea with the eyedropper, but it didn't work. I ended up using the brush tool to desaturate the color, which really helped neutralize the yellow. But thanks so much for the good ideas!

For my 2 cents worth, I would select the yellow area with the oval select tool, set feather as necessary (depending on the image resolution, maybe 20) then click add adjustment layer, levels, and color correct (+ blue) as needed. Let me know if you need help. Vince

1. In Photoshop, go to "Layers"--> "New Adjustment Layer"--> "Selective Color". Click "Yes" to the popup. 2. On the drop down menu at the top, go to "Yellows". Slide "Black" to the left quite a bit. You will see the entire picture lighten. Then slide the "Yellow" slider (Still under "Yellows" in the drop-down) to the left. The colors will be a little odd for the rest of his face; only pay attention to the yellow part for now. Adjust the sliders until the yellow has been mostly eliminated. Click "Okay" to close the layer. 3. On the "Layers" panel on the left, select the "Selective color" layer you just created. There should be a white box to the right--the layer mask. Hold down alt-shift and click on that white box. Select the brush tool and paint over the NON-yellowish part of the picture. It will show up a red mask on that part. When finished, alt-shift-click again on the white square (which shoul dnow be mostly black)> The red will disappear and the colors should be right. 4. Layers=> Flatten image. Save. Hope this helps! Selective color is one of those thing a lot of people don't know about, but its a pretty powerful tool. Elaine

No problem. It's also very useful for dealing with noise; what you are essentially doing is altering the color balance within a set range of colors; ie, the black pixels in the yellow parts of the image, or whatever. Since digital noise likes to hide in certain color channels, you can use it for that; ie if you have blue or green noise in the shadow areas you can do "Selective color"--> "Blacks" or midtones and then reduce the blues and greens within the black areas of the picture.
