Summary

Whenever we are creating content on Confluence, hyperlinks cannot be differentiated from surrounding text if the user is using some sort of accessibility extension.
The only way a colorblind or low vision person has to differ this content on pages is when they hover the mouse cursor over the text.

Suggestion

Change hyperlinks to be compliance with WCAG:
Understanding Success Criterion 1.4.1: Use of Color: explains that color should not be "used as the only visual means of conveying information, indicating an action, prompting a response, or distinguishing a visual element."
