xterm colour schemes

xterms suggested colour schemes:

green on black
black on wheat
white on navy
cyan on black
orange on black

He uses white on navy for emacs.

In a series of experiments, proofreading performance was consistently
better with positive polarity (dark text on light background) than
with negative polarity displays (light text on dark background). This
positive polarity advantage was independent of ambient lighting
(darkness vs. typical office illumination) and of chromaticity (black
and white vs. blue and yellow). A final experiment showed that colour
contrast (red text on green background) could not compensate for a
lack of luminance contrast. Physiological measures of effort and
strain (breathing rate, heart rate, heart rate variability and skin
conductance level) and self-reported mood, fatigue, arousal,
eyestrain, headache, muscle strain and back pain did not vary as a
function of any of the independent variables, suggesting that
participants worked equally hard in all experimental conditions, so
that the interpretation of the primary performance measure was
unlikely to be contaminated by a performance-effort trade-off.
