Ironically, I find some validation for this in the OS X 'Universal Access - Switch to White on Black' help information which confirms that this type of display is easier to view.
I have done some searches here and played with my newly purchased NWE, but have not been able to set the text to display this way without compromising the printed version....you can choose different screen contrasts to make the screen easier to view. Choose a screen contrast effect in the Universal Access pane of System Preferences.
Choose Apple menu > System Preferences and click Universal Access. Then click Seeing.
To remove colors from the screen, click "Set Display to Grayscale."
To make the computer screen appear as a photonegative (with white text on a black background), click "Switch to White on Black."
It's nice to be able to set the Draft view background to black, but I assume that there's no way to change the text to, say, light green without also coding that color into the Page View and printed versions of the doc.
-If I'm wrong, I'd love to know how to do this.
-As I've always been in the minority on this, I don't suspect there'd be a lot of support for putting this feature on the development list. I simply have never understood why people want that Cathode Ray Tube, (or flatscreen now) shooting maximum white light into their eyeballs. Black is so much more soothing. Just my 2 cents. Thanks for any responses that share my preference.
