means for displaying a cursor on said display screen;

cursor control means for controllably moving said cursor on said display screen;

start position specifying means for selectively specifying a first position where said cursor is located by said cursor control means as the start position of a desired editorial area;

end position specifying means for selectively specifying a second position where said cursor is located by said cursor control means as the end position of the desired editorial area;

first storage means for storing positional information as to the start position of an editorial area specified by said start position specifying means;

second storage means for storing positional information as to the end position of the editorial area specified by said end position specifying means;

color specifying means for specifying and storing in the form of color setting information the display color and background color of characters included in an editorial area of said document in response to operator selection, said editorial area being specified by the positional information stored in said first storage means and the positional information stored in said second storage means; and

color information processing means for updating the contents of a portion of said color information storing means which corresponds to said editorial area of said document, on the basis of color setting information stored in said color specifying means, whereby dot pattern data stored in said dot pattern refresh memory means is modified in response to said updating of said color information storing means.
