Links are very hard to distinguish from ordinary text in API documentation with the default stylesheet. The color used for links is a pale blue (#4A6782) while block text uses a very dark gray (#474747). We could increase the distance between these colors by making the text color darker and the link color lighter and/or more intense.

The first attached screenshot shows a paragraph containing three links ("identifier", "name", and "changed"). The second screenshot shows the same paragraph with slightly darker text and brigher link color.
