  Unit:     Crt
 
  Context:  HighVideo, LowVideo, TextBackground, TextColor
 
  Description
 
    The Crt unit defines color constants for convenience. Colors are
    represented by numbers. Pass a selected color to TextColor or
    TextBackground.
 
    The numbers 0-7 represent colors for foreground and background. The
    numbers 8-15 represent high-intensity versions of colors 0-7. They
    are used for foreground only.
 
    Use HighVideo and LowVideo to switch foreground colors to high or
    low intensity.
 
    Set blinking text by passing the constant Blink added to the
    specified color.
 
    Monochrome monitors display foreground colors as modified output of
    monochrome text. Colors may be translated into dim or bright text,
    possibly with underlining. The translation depends on the particular
    monitor and graphics card.
