       _i_._c_o_l_o_r_s allows the  user  to  interactively  assign  red,
       green,  and  blue  colors  to the band files in an imagery
       group while viewing the display of the combined	bands  on
       the graphics monitor.


       The  user is asked to select an imagery group.  Band files
       in the group that  are  currently  assigned  to	the  red,
       green,  and  blue color bands are displayed along the left
       edge of the user's graphics display frame, and a composite
       image  of these bands is displayed in the right portion of
       the display frame.  A small matrix appears  in  the  lower
       left  portion  of  the display frame, and reflects current
       red, green, and blue band file  color  assignments.   Red,
       green,  and  blue  color boxes appear next to the names of
       the image band files to which they are currently assigned.
       The  user can change current color assignments by clicking
       the mouse cursor beside desired color assignments.


       A menu along the bottom	of  the  graphics  display  frame
       indicates  that	the  user can also replot and enlarge the
       composite image on display, or quit the program, by click-
       ing the mouse cursor on the desired option.


       The  GRASS program _i_._g_r_o_u_p can also be used to assign red,
       green, and blue colors to imagery group band files.

       This program is not yet complete.  To assign colors to  an
       imagery group use the GRASS program _i_._g_r_o_u_p.


       This  program  is interactive and requires no command line
       arguments.  The user must be running a graphics monitor to
       use this program.


       To  store color composite output into a map, the user will
       utilize _i_._c_o_m_p_o_s_i_t_e.
