The story of why hyperlinks are blue and because when


Take a second to assume the way you mentally visualize a link; we display this idea in one of these ways with the adjective ‘blue’ that after 5 years in the past, Google dared to “paint” theirs black, it was once so surprising that the subject turned into information.

Cleverly it’s true that since CSS taste sheets exist, hyperlinks will have any color and structure, however blue (and underlined) is the default appearance of links in all browsers (or even in sentence processors, reminiscent of MS Phrase). And this since… intelligently, perpetually. Or more ?

It’s fascinating ask about when and ‘why’ you got in touch – in no way more stated – the idea of ​​link with the color blue, because this idea predates the generalization of color displays.

A few weeks ago, on the Mozilla company blog (the root that evolved the Firefox browser) they had tried to answer this request, putting together a complete sequence of serious hobby information.

Once upon a time there was the link (but it wasn’t dark blue)

The link was born once even before the vast international internet or similar private computing, with the Xanadú Challenge in 1964, although it is true that it has by no means gone beyond the theoretical stage.

First step in the international sense of the links obtained here from the HyperTIES publication tool (for DOS techniques). And of course, already then they were blue … but cyan blue, is no longer the everyday color of blue that we are using lately in Internet hyperlinks.

When Windows 1.0 allowed the landing of “full” color graphics interfaces, it also had under the arm another part that we use lately: links with underline. However, these links were still black, despite the extensive use of blue in headers and window borders.

When Tim Berners-Lee started painting on his International Vast Internet business two years later, his WorldWideWeb browser (written all in combination) featured links are underlined, but still appear black and white.

‘# 0000FF’ is the hexadecimal code for the dark blue of our links

When Apple and Microsoft made fashion and Mosaic joined

The sequence of blue to links had to wait until the 90s, as interesting as it is from the hand of Apple and Microsoft, and no longer from the newly donated Internet browsers: the tool Apple’s HyperCard has already colored its hyperlinks dark blue after being clicked (even though they were still black by default) and Windows 3.1 did the same with icons in 1992, used to standardize the hyperlink between blue and the interactive parts of the interface.

12 months later, in the end, the 0.13 model of the Mosaic browser introduced in its list of settings adopting blue links with constant underline for unvisited hyperlinks, and pink with damaged underlining for those already visited.

In the same year, the Cello browser also followed the “blue underlined” glance … For the next 12 months (1994), each cello and baby Netscape Navigator followed the “usual” birth imposed by Mosaic.. Web Explorer did the same when it was born in 1995.

On the other hand, if the “when” has been sufficiently intelligently established, the why remains unknown. It cannot be attributed to a standardization criterion W3C, as it was only created in 1994; and the distinction ratio between dark blue and black textual content is 2: 3: 1, manifestly insufficient if the distinction was the aim pursued.

Subsequently, the justification must be sought in different places: the whole turns out to mean that Mosaic builders joined a development that had already been introduced “offline” by Apple and Microsoft, to link “blue” and “interaction”.
