In film industry, the application of symbolism of color can construct the film color ideographic function symbols, while using the nonsymbolism of color can highlight the color thinking of film artists. The combination of the symbolism and nonsymbolism shows the following two aspects of the effect: one is to achieve the twodimensional color matching (focus on symbolism); the second is to realize the threedimensional construction of film color (emphasis on nonsymbolic). BlowUp by Antonioni is a masterpiece of the combination of symbolism and nonsymbolism in color application, and his unique mindset of sensing and using color provides excellent reference to his successors.
