I have seen pages where the link color was changed to red and where links
are only distinguished bei mouse over and focus effects. I have also seen
color blind people looking at that page and saying "No, there are no links
on this page." The color red is probably a specific case, because some
people with color blindness see red asblack or dark grey.

But even people using contrast mode may have difficulties. Althouh there are
all kinds of settings which can be made for links, links that are only shown
in a different color may be overseen. So it is important to add at least one
more visual cue (icon, underline, font weight ...) to the visual
presentation of the link - specially when the links are a part of other
text. 

That is how I understand 1.4.1. If links don't have at least one visual cue
other than color, then the page fails conformance level A.
