Are all links able to be identified as links by something other than color alone?

Goal

Ensure that all users can identify links on the page.

Why this matters

Users with Color Vision Deficiency (Colorblindness) may not be able to identify links if the only thing that differentiates them from body copy is the color.

How to implement

UX Designer

Review Using color, especially the section on link color.

Developer

Implement the Designer’s requirements for links using CSS.

How to test

1. Review Using color, especially the section on link color.
2. Ensure you understand how the Designer intends to meet the requirements with their documented design. Confirm that color contrast ratios meet the requirements outlined in Using Color. (If the requirements the Designer is providing are bad, the code will be bad as well.)
3. Assuming the Designer’s requirements are met, confirm that the code was implemented to meet the Designer’s requirements.
