So why are the hyperlinks blue anyway?
You may have already noticed that while some links are gold and/or bold, most links are blue, especially on old web pages. But why? TL’s answer; DR is that the Mosaic browser, released in early 1993, used blue links, and since the browser was widely distributed, blue became the norm. OK very good. But why did he they or they choose blue? It’s a question that requires a deep dive into technology through the ages as the web and personal computing have developed in tandem..
It’s important to remember that the idea of hyperlinks predates the invention of color monitors, which thickens the plot a bit. But the focal point seems to be Windows 3.1, released on April 6, 1992, when hyperlink blue became a navigational and interactive color. A year later, the April 12, 1993 release notes for Mosaic include a bullet point that becomes the point of origin for the blue hyperlinks:
Changed default anchor representations: blue and single solid underline for unvisited, dark purple and single underline for visited.Mosaic Release Notes
Around the same time, the Cello browser was developed at Cornell Law, which also used blue hyperlinks. Thus, the blue hyperlink concept was arguably browser-independent even before the advent of Netscape Navigator and Internet Explorer.
The writer speculates that blue was chosen to stand out from black and white once color monitors took over, and that seems legitimate to us. Can you imagine blue hyperlinks on Hackaday, though? Ouch.
