FILL="r,g,b"

The color for filled areas, where each of the three values (red, green, blue) must be in the range 0 to 100 percent,

or

FILL="colname"
where 'colname' takes one of these values:

CYAN

MAGENTA

YELLOW

BLACK

RED

GREEN

BLUE

WHITE

or NONE to turn off filling.

FILL may be used in TEXT elements to place the text on a colored background. The filled area will be a rectangle just sufficient to underlie normal characters. PADDING may be used to extend the area. ROTATE may be applied too, though while the resulting IDF document will print correctly, some systems will be unable to display it properly on screen.
