Set of 4 Geometric Acrylic Earrings

I am so disappointed in the colors. The catalog pictures a variety, where as the earrings I received are all exactly the same color palate. I really wanted the color variations as shown and loved the lime greens in the long ones, the orange gold triangles and the red and turquoise in the round. The pictured selection is beautiful, mine are not. Why have 4 different pairs of earrings when they are all the same exact colors?
