Here’s an interesting and unexpected result. Do a google image search for “tech”. You will, at the time of writing, get something like this:
Tech is clearly blue. The same is true for “digital”:
and for “cyber”:
I had to make sure that the search-by-colour filter was turned off. This is really surprising to me. I have seen lots of these kinds of images before, but I am gobsmacked at how dominant this colour scheme is as a way of depicting technology. Where does it come from? Some vague notion of “computers are made of electricity, and electricity looks something like a lighting bolt going across a twilit sky”? The second choice seems to be some kind of green-screen terminal green, which is vaguely comprehensible; but, even so, odd. I am in my forties and probably of the youngest generation to have used a terminal for real, and even then only for a few years whilst I was at university.
I wonder what other hidden colour schemes there are out there?
Aside: our university timetable still calls classes held in a computer room “terminal” classes. I wonder what proportion of the students would have any idea why they have this name? I suspect that the vast majority just take it as an arbitrary signifier, and have no idea of its origins.
