Color Alone, Color Contrast, Color Conflicts
Position (continued)
Is a color difference between a visited link and an unvisited link a failure of Use of Color?
From Non-text Contrast:
there is not a new requirement that visited links contrast with the default color
Also from Non-text Contrast:
does not require that changes in color that differentiate between states of an individual component meet the 3:1 contrast ratio when they do not appear next to each other
Does it need to meet the 3:1 contrast ratio when they do appear next to each other? If so, how much is "next to each other?"
