Complementary is a color scheme using one base color and its complement, the color on the exact opposite side of the color wheel. The base color is main and dominant, while the complementary color is used only as an accent. A combination of one warm and one cold color is always created.
 
        
                    
             
        
        
        
Down bow or Giù arco
Like sull'arco, except the bow is drawn downward. On a plucked string instrument played with a plectrum or pick (such as a guitar played pickstyle or a mandolin), the note is played with a downstroke.
