I'm processing some kid candids and I have a perplexing problem. The kids were sliding face-first down a yellow water slide into the lake and in one of the pics, the yellow threw a noticeable colour cast onto the lower face and the nostrils of the subject, who is black. Any suggestions? (I have Aperture 3, the Nik Collection and now GIMP to work with.) I am reluctant to post the photo on a public forum without the parents' permission. If you can point me to any resources about processing skin tones generally, or black skin tones in particular, I'd be grateful.

You should be able to do this in lightroom. use your quick selection tool to pick the color cast area, then copy that isolated area. In the filter dialogue, go to blur-average and do a control I to invert the selection which should make the color cast go away. flatten all the layers.

Use the Nik remove color cast setting on a duplicate GIMP layer then mask outte areas not affected back in GIMP.

I recommend that you upgrade from GIMP to a commercial photo editor. GIMP was developer originally as a tool for web graphics creation and unless you have a new version of GIMP where they addressed this, the maximum channel depth is only 8 bits ( JPG Color Depth ). This will provide full color for web graphic work, but is insufficient for photography.

Plus, I assume whatever I learn from GIMP will be transferable, so I don't think my time will be wasted. Then there's the fact that the opposition party in government is threatening to hold up my paycheques, so I am counting my pennies at the moment...
