COLORS(1)                                               COLORS(1)

     NAME
          getmap, colors - display color map

     SYNOPSIS
          colors [ -rx ]

          getmap [ colormap ]

     DESCRIPTION
          Colors presents a grid showing the colors in the current
          color map.  If the display is true color, colors shows a
          grid of the RGBV color map (see color(6)).

          Clicking mouse button 1 over a color in the grid will dis-
          play the map index for that color, its red, green, and blue
          components, and the 32-bit hexadecimal color value as
          defined in allocimage(2). If the -x option is specified, the
          components will also be listed in hexadecimal.

          The -r option instead shows, in the same form, a grey-scale
          ramp.

          A menu on mouse button 3 contains a single entry, to exit
          the program.

          On 8-bit color-mapped displays, getmap loads the display's
          color map (default rgbv).  The named colormap can be a file
          in the current directory or in the standard repository
          /lib/cmap.  It can also be a string of the form gamma or
          gammaN, where N is a floating point value for the gamma,
          defining the contrast for a monochrome map.  Similarly,
          rgamma and rgammaN define a reverse-video monochrome map.
          Finally, the names screen or display or vga are taken as
          synonyms for the current color map stored in the display
          hardware.
