Change custom text and background screen colors?

If we choose to use our own text for the splash screen, is it possible to change the text and background colors?
Currently, it uses a white background with black text.
This is not good because using a white background requires the monitor to "work" very hard. (All pixels on the monitor are activated.)
It would be better to have a black background with white text. (And then make the text "change location" every few seconds, so it prevents "burn in", and also gets people's attention, too.)
Thanks!
