Our “link blue” had never shown up in user interfaces before 1993, and suddenly it appears in two instances within two short months of each other in two separate browsers at two different universities being built at the same time.
Blanchard believes that the real reason behind the push was Windows 3.1 and the support for colour monitors.
Mosaic came out during an important time where support for color monitors was shifting; the standard was for hyperlinks to use black text with some sort of underline, hover state or border. Mosaic chose to use blue, and they chose to port their browser for multiple operating systems. This helped Mosaic become the standard browser for internet use, and helped solidify its user interface as the default language for interacting with the web.
