Links contain text, but they should never look like text. When users read a web page, they need to be able to distinguish what’s clickable. If your links don’t have enough contrast, users could miss them.Color is Not Enough for the Colorblind
Most sites make their links a different color from their text. But that’s not enough contrast for colorblind users. The difference in color is hard for them to see. Colorblind users have to rely on their cursor change (arrow to hand) as feedback.
A hover effect can give them a clear signal to see what’s clickable. When users move their cursor over a link, they’ll notice a change in color or shape that tells them to click. This prevents them from missing links.
