Yellow Stains on Shirt

[Stephanie]

Hello! I was wondering if there is anything I can do about the yellow stains on this little guy's shirt?

First, add a Channel Mixer adjustment layer, check the "Monochrome" checkbox, then enter 0/+100/0 for the values.  This will turn the whole photo black-and-white.

Then add a Levels layer, and immediately clip it to the Channel Mixer layer (Ctrl Alt G).  Enter these values:

• Red channel: 0/0.40/255 and 0/195
• Blue channel: 0/0.80/255 and 0/245

Then return to the Channel Mixer layer and invert its mask to black, then paint over the shirt in those areas.  Don't be too precise, big and soft is better at first.  Then you'll need to be more precise painting with black to prevent the skin and buttons and little boats from turning green.
