Correcting small areas of color cast

I have an older picture of a Pileated Woodpecker under uneven foliage that I would like to salvage. Where the light is direct (unfiltered by the intervening leaves) the feather color is 72, 57, 62. However, in a few areas of the bird, the light is either filtered by the foliage or reflected off foliage and the feather color has a greenish cast (65, 69, 21). I was able to create a soft mask over the greenish areas, and now I would like to "dial-in" the desired color (72, 57, 62).

I no longer have the problem with my newer shots because I now use a Harbor Digital flash extender and do not rely on variable light.

  You can use the Add Color Readout tool to drop an RGB color readout on your feathers with the color cast and then use which ever color correcting method you prefer (Color editor, color balance, white balance, levels/curves) to move the color to your desired RGB readout.
  
  In the future you might also consider using the Color Editor tool to select the color you'd like to adjust and then select "Create Layered Mask From Selection" to create the layer & mask.

  Try the skin tone tab in the colour editor. Click the colour you want everything to be then adjust the sliders under uniformity.
  That tab should really be renamed Uniformity since it works in lots of scenarios outside of skin tones.
  Make the changes on a layer so you can mask just the bird and also adjust opacity if required to restore some subtle variations if appropriate.

  In Capture One 11.1, there is also the very powerful "Normalise" tool.

  I just gave, "Normalize" a try. First couple of attempts produced psychedelic images, but I am closing in on the desired effect.
  Thank you, all!

  Someone please correct me if I'm wrong, Normalize is for matching white balance and exposure of two separate images. It does not have any effect on adjustment layers, only the background layer. If you use it with in a single image you will just be changing your exposure and white balance based on your selection point, hence the "psychedlia", which would be no different than moving the white balance & exposure sliders.

  You are right, "Normalise" tool can't be used in layers. I have however recovered the same color for an object between two images using it, but it changed a little bit the colors of the background. Actually, the two colors were not so far from each other.
