KitchenAid’s stand mixer is available in over 32 colours. To promote this, we put a colourful digital billboard near the CN Tower - Canada’s architectural icon and the world’s largest free-standing structure until 2007.Every night the CN Tower lights up in a myriad of colours. Using technology that watched the CN Tower’s colour we then matched it to one of the stand mixers over 32 colours and updated the billboard in real-time.
