Accessibility Features of iOS for the iPad and iPhone

Black on White: Black on white is the next feature, and I have here in brackets [invert color.] I want to explain what that is. Black and white is what the name of the feature is, and you can turn it on. Basically what that does is it inverts the color of the screen.

If you’ve got black text on white background, then you do get black on white, meaning it will go to a black background and white text. This is really good for those users who need high contrast screens.

The invert color, what it really does is if you have colored text or color image, it will make it the opposite on the color wheel. So, blue would go to… I can’t think of the opposite on the color wheel of blue, but with black text on a white background, you get a really high contrast. When you’ve got colored text on a colored background, the contrast may not be so high.

You’ll have to experiment as to which programs this works well for you. It does not make everything black and white and make it super contrast like it would on a desktop application. It just inverts the color. Again, you need to do some experimenting to see if this works with every program that you want.
