> saves energy

As far I understand this is not true. Can anyone smarter than me comment?

Some of the phone screen technologies such as AMOLED also save power with black.

It depends on the type of screen you're using and whether it's actually black - rbg(0,0,0) or just dark. In some cases, yes, it saves energy, some not.

I would disagree that it's not easier on the eyes. At least 98% of dark-background designs. Perhaps this is just preference/different eye thing.

They only save energy if you are using a CRT.

As mentioned above (by guelo), an OLED screens power consumption also varies with the gray level of the displayed image.

Not to mention it's just a breath of fresh air design-wise (when executed well), unlike the massive sea of indistinguishably homogenous 'light-themed' sites...

EDIT: I can't believe people seriously downvoted you for that simple comment. The pedantic negativity this community is filled with is ridiculous sometimes.

It's probably based on the factual inaccuracy of the energy saving claim.

Which can be (and was) remedied by a simple reply to correct that one particular part. Indiscriminately pedantic downvoting on the other hand, just kills the potential for any fruitful discussion all for the sake of some silly minor mistake. Luckily, more people came in and got the comment out of the grey zone in this case.
