For usability and accessibility, links should be underlined by default. Otherwise, link text must have at least 3:1 contrast with surrounding body text, and must present a non-color indicator (typically underline) on mouse hover and keyboard focus. 

This tool allows you to check if link color meets WCAG 2.1 standards.
