This piece by Prachi Jain combines bright tones of a color with dull tones of the same color. The piece uses a combination of primary colors in the top and bottom sections with tertiary colors in the left and right sections. The brighter colors in the top and bottom sections are intensified by the dull colors used in the left and right sections because the dull colors are sort of drab so they make the bright colors seem even more energetic than they already are. In the case of this piece the artist used a hue to create the difference in the sections. The saturation of the colors makes the bright red look brownish in the dull sections. Different values are also displayed in the piece with the use of the bright green, red, yellow, and orange; these colors are all light and unstable so they keep the eye moving around, where as in the dull sections the color combinations are more stable because of the drab colors. The colors used in this piece are complementary, which can be seen with the color interaction between the green and the red in the top and bottom sections.
