Both are right
Authored by: dzurn on Dec 05, '02 12:35:07PM

The White-on-Black option in Universal Access seems to
have changed functionality since I first tried it several
months ago.

I'm running 10.2.2 now and the "White on Black" option
REALLY DOES reverse the polarity of the screen. It also
sets it to 256 colors instead of thousands or millions
on my CRT monitor. Looking at the digicam shot in the
hint shows it to be back to its correct color.

Months ago the White-on-black feature switched to a
negative greyscale, not negative full-color. That seems
to be the big difference in what people are reporting.

Try Cmd-Opt-Control-8 and see what happens. I don't know
if flat-panel LCD displays would work differently.

This works the same on my laptop, so i would assume it's independent of the veiwing device. Makes sense really -- how and why would the OS know to treat a CRT differently from an LCD?

What i don't get is, why use 256 colors to "improve" visibility?

Why results might be different

Apple just released a Tech Note with this line:
You see a negative image in the screen. Depending on system configuration, it may be black and white, such as that in Figure 1, or color negative, such as that in Figure 2.

I was fooling around and found this out. Invert the screen using the universal access shortcut, and then change the color settings (I used the monitor menu extra, if it makes a difference.) On my screen I get millions of colors inverted. Sweet!
