paper.
SO, while it may be true that many years ago people were used to mainly reading black text on white, it wasn't a matter of "conditioning" per se.
People simply recognized the contrast between the text and the background, in the same way that a line drawn in the sand can be better seen when the
sunlight makes a stronger shadow. Simply put, the better the contrast, the easier it can be to read the text. (Not always, though, if the colors are
too garish.)
But even if we want to argue the "conditioning" point, things have moved on. We don't just read text in books, but in magazines, on packaging,
street signs, billboards and so on. I have magazines like National Geographic where they sometimes use different-colored backgrounds and text colors.
As for packaging, just in my kitchen I have coffee jars with white text on brown background, cornflakes (generic) with dark blue on light blue, and so
on and so on.
And how many road signs have black text/symbols on a white background?
However, on a computer screen rather than in the "real world", dark
is better for the reasons others have mentioned. These screens throw
light at our eyes so when we read for long periods it's good to reduce the amount of it. Also, as the screen is dark until pixels are lit by the use
of energy, it makes sense to me that if we have a predominantly dark screen with lighter text on it, then the computer should be using a little less
energy for display. It might not seem significant, but considering our large and still-growing membership, it's a useful energy saving.
So -- dark for me!
Just a request/suggestion if I may: a few members have avatars that "flash" in bright and varied colors at a rapid rate. I have an epileptic
condition and just seeing such an avatar by the text makes me feel very ill, very quickly. Covering it up with a strip of heavy paper is an option but
that doesn't help if I get caught unawares. I'm certainly not the only member who has such a condition so I'd like to ask if there is a way we can
disable any avatars that "flash" or "pulse"
before we enter the forums. I don't like "ignoring" people just because of their avatar.
