Working Group Resolution (LC-2881):
Thank you for the comment.  You are correct in stating that 1.4.1 does not
allow for information to be conveyed by color alone, and that is what this
technique seeks to address.  Using this technique, in addition to color
being used to identify links from surrounding text the relative luminance
difference of 3:1 or greater (paired with additional confirmation when the
user tabs to or hovers over the links) allows the links to meet 1.4.1.  

To help make this more clear, we are adjusting the applicability sentence
Colored text when color alone is used to convey information such as words
that are links in a paragraph
Text with links which lack decorative effects such as underlining that
typically serve to help users identify links from surrounding text.

We will leave this as a sufficient technique.
