RESEARCH ON COLOUR WHEEL

colour wheels are often used for education and design purposes. Using a colour wheel and have customers spinning the wheel to choose which colour of food they should buy would be a convincing idea. The simplest colour wheel is divided into 7 colours, the rainbow colours. Red, orange, yellow, green, indigo and violet. Some complicated colour wheels will even show different tones of the specific colours. 
--> could correspond them to specific food in that colour
--> have people spin the wheel to help them choose what colour they should buy each day
--> like a game to play every day to make people feel excited and curious about what colour they would spin onto
