/*
 * These are default colors that you'll get when you turn
 * color on. The way color works is that the closest possible
 * RGB value is chosen so these colors will produce different
 * results in the different color models (the 8-color, 16-color,
 * xterm 256-color, and PC-Alpine color).
 * See init_color_table() for the RGB values we use.
 * The 8-color model uses the 8 0 or 255 possibilities. So,
 * for example, if the default color is "000,217,217" the
 * closes 8-color version of that is going to be "000,255,255".
 * In the 16-color terminal we use 000, 174, and 255 as the
 * possible values. That means that a default value
 * of "000,214,000" maps to "000,174,000" (a dull green)
 * but "000,215,000" maps to "000,255,000" (a bright green).
 *
 * The colors which don't have defaults map to either the current
 * setting of the Normal color or the current setting of the
 * Reverse color, depending on what we thought was right long ago.
