The Central metaphor of the pantone campaign is to show that pantone colors are like ballerinas. The company picked this metaphor because the colors have movement and can be combined with other colors to create a scene or express emotions, just like ballerinas. The message is effective because I see the different shapes and strips that show movement and the temperature of the colors and lights that help express emotions, just like a ballet show. As for designers they use colors to express all this.
