The expressive colors image is to describe my favorite city - Shanghai. I basically seperate this image into two main parts.  The right bottom part is composed of the light colors green and yellow, which express the joyful and exciting aspect of the city. The left top part is composed of red and blue, with relatively low values. This is to express the clutter and high working pressure in the city. Overall, the colors are saying it’s a fast developing place, with very rush pace in daily life and many opportunities to expolore. In the picture, light colors are neighbored with dark colors, saturated colors are next to unsaturated colors, just in order to give the feeling of fast changes and full of suprise, which are the features of this city.
