// This table is initialized with color values I got by reading the
// colormap on an IRIX 4.3 machine:
// "full intensity colors" have been turned down some to make white
// background less intense by default. The hope is that this will make
// fltk programs more friendly on color-adjusted screens. If you want
// pure colors you should get them out of the colormap.
//#define III 244 // maximum intensity of the basic colors
// that results in errors and unshared colormap entries, so full intensity:
#define III 255 // maximum intensity of the basic colors
static short cmap[256][3] = {
// 3-bit colormap:
{ 0, 0, 0}, // black
{III, 0, 0}, // red
{ 0,III, 0}, // green
{III,III, 0}, // yellow
{ 0, 0,III}, // blue
{III, 0,III}, // magenta
{ 0,III,III}, // cyan
{III,III,III}, // white
// pastel versions of those colors, from SGI's standard color map:
{ 85, 85, 85}, // 1/3 gray
{198,113,113}, // salmon? pale red?
{113,198,113}, // pale green
{142,142, 56}, // khaki
{113,113,198}, // pale blue
{142, 56,142}, // purple, orchid, pale magenta
{ 56,142,142}, // cadet blue, aquamarine, pale cyan
// The next location is used for FL_SELECTION_COLOR. It formerly was 2/3 gray
// but this is changed to be the Windows blue color. This allows the default
// behavior on both X and Windows to match:
{ 0, 0,128},
//{170,170,170}, // old 2/3 gray color
// These next 16 are the FL_FREE_COLOR area. In some versions of fltk
// these were filled with random colors that a Irix 5.3 machine placed
// in these locations. Other versions of fltk filled this with the 1/3
// gray above to discourage their use. This newest version uses colors
// that NewTek has assigned for their GUI:
