Settings>General>Accessiblity>White on Black *On*?

[Unspoken Demise]

What is the purpose of this setting? My dad and I were trying to figure out who this makes the iPhone more "accessible" to. Maybe color blind people?

The screen capture function wont show the color of the screen but it makes it black and orangeish. Then the springboard becomes white not back, and everything is funky colors, including apps and website. The whole phone gets colored a different way.

I tried searching "white on black" but everything that came up was some kid asking everyone what color iPhone he should get.

In any event, it looks cool and worth looking at, but does anyone know its function?

EDIT: Yes, I have a 3Gs. The signal in my office sucks really badly, so I'm on Edge.

I believe it is a disability setting for those who have a strong light sensitivity. You can also set this on a mac by hitting: command-option-control-8.

I don't have any eye problems, but I use it at night & its easier on the eyes for easy reading.

What its doing is reversing all the colors, so its (i believe) on the opposite end of the color spectrum.

It inverts the colors. Some people have an easier time reading white text on a black background. This feature has been in OS X for the longest time.

control + option + command + 8 does it in OS X.

Oh, well I've never owned any Mac/ Apple products other than the iPhone, and neither has my Dad, so it was new to us. Thank you for your responses. Its still pretty cool to look at. And I can also play a joke on my girlfriend and make her believe she messed up my phone

Cool, never noticed this before. I wish it didn't make everything all ugly though. I really like the purple battery icon and the orange 3G icons though!
