Somehow I can't post all of the reply as a single message
(getting some "database error").


3. you should use more contrast colors as the char shapes (in the
   16x16 table) and other UI elements aren't very legible;
   I found approximately 40 usable color pairs in about 128
   color combinations available for regular text modes
   (8 darker colors for background and
   16 darker and brighter colors for foreground) using this
   simple technique:
   1. List all colors by their luminance using the formula
      R=.3,G=.6,B=.1
      Color    GRB  Luminance(G=.6,R=.3,B=.1)
      black    000  0.0
      blue     001  0.1
      red      010  0.3
      magenta  011  0.4
      green    100  0.6
      cyan     101  0.7
      yellow   110  0.9
      white    111  1.0
      (note, G and R are swapped here)
   2. Assuming bright colors' luminance is approx. 30% higher,
      include bright colors in the list:
      Color   brightness GRB  Luminance
              (+30%)          (.6+.3+.1)
      black            X 000  0.0   \
      blue             0 001  0.1    \ dark
      Blue             1 001  0.13   /
      red              0 010  0.3   /
      Red              1 010  0.39  \
      magenta          0 011  0.4    \ middle
      Magenta          1 011  0.52   /
      green            0 100  0.6   /
      cyan             0 101  0.7   \
      Green            1 100  0.78   \
      yellow           0 110  0.9     \
      Cyan             1 101  0.91     } bright
      white            0 111  1.0     /
      Yellow           1 110  1.17   /
      White            1 111  1.3   /
   3. Now choose pairs of colors such that the colors in each pair
      are approximately 0.6 or more away from each other in terms of
      luminance.
