palette = Hardware color palette, stored as 16 words.  First word is
          color register zero (background), last word is color register
          15.  Each word has the form:

          Bit:  (MSB) 15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00 (LSB)
                      -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
                       0  0  0  0  0 R2 R1 R0  0 G2 G1 G0  0 B2 B1 B0

          R2 = MSB of red intensity
          R0 = LSB of red intensity

          G2 = MSB of green intensity
          G0 = LSB of green intensity

          B2 = MSB of blue intensity
          B0 = LSB of blue intensity

          Intensity ranges from 0 (color not present) to 7 (highest
          intensity).

          Example: { red = 7, green = 3, blue = 5 } -> 0735 (hex)

          Caveat:  It is wise to mask off the upper four bits of each
                   palette entry, since a few programs store special
                   information there (most notably Art Studio).
