The Hue Curves tool can do what you want. It's a little bit complex if you've never used a tool of its kind before.
Drag the pick button to the Viewer to choose the hue you are targeting; just clicking it won't do anything. A new spline point will appear in the graph with an inverted triangle marker rather than the square default markers. Set the tool up to affect only the qualities you want to change—hue is a likely one—with the checkboxes at the top. Then drag the picked spline point up or down to change the targeted color.
As with all curve tools, it's sometimes easier to manipulate it in the Spline View. In this example, you'll notice that I picked up some of the dirt in my correction. A rough luma key off the blue channel would probably do to clean that up.
