Was hoping for the answer, too. I’ve created and activated my child theme and have diligently added code only to my child. I’ve looked around in the docs, forums, and searched elsewhere for it. No luck.
I’m using Twenty Eleven, dark, and have come across the “!important” trick for changing colour values in my menu bar, etc. That works quite nicely.
I’ve changed the colour of the page’s body text to suit my site, but I would also like to change the page title colour, and the colour of the links (to other pages and websites) within the text. When I tried to change the colour in the “Link” section. Unfortunately that also changed my menu text colours and some of the colours in the admin bar above my site (when I was logged in).
Stumped.
