Could you let us have a small set of files set up like your document as well as a description of the order you are doing things to see the behavior. Does this happen if you open the root file directly? What are your `Project Root File' settings (TeXShop->Preferences->Misc)? Etc.

I had no intention of implying that TeXShop should know about multiple files when I open the root file.

No neither of the files is syntax coloured regardless which one I open first.

However they are coloured on OS X Yosemite.
