Back in the day, a vivid blue and a royal violet distinguished available and visited links on the majority of websites. Even simple pages often took many seconds to load, and the assumption was that purple helped the user know where they had been and where they were going.
Today, we've largely left behind the default blue colors for links, leading to a variety of both helpful and harmful design trends. Much has been written about making click targets discoverable and accessible, but I'm having trouble finding contemporary resources for visited states.
My question is threefold:
In the age of SPAs and dynamic content views, should we be styling visited links at all?
With contemporary design leaving the blue behind, and with accessibility concerns placing increased emphasis on form over color, are there better alternatives (e.g., text styling) than the classic purple?
Is there anything about contemporary sites still making prominent use of blue-vs-purple (like Craigslist) that sets their use cases or user scenarios apart from other sites and apps? Does this set them apart from their direct competitors (like Letgo) who don't style visited links?
Thanks in advance!
