Three varieties of Mott's Clamato, No Frills, Vancouver, BC

Colour is commonly used as a signalling device by brands. Yellow is the colour of the leader's jersey at the Tour de France, brown is UPS's signature colour, and Ferrari is known around the for its signature red.

Mott's has just introduced a new flavour of Clamato. The firm uses the blue lid colour to indicate the original flavour, the red lid colour to indicate the Extra Spicy flavour. And now with the introduction of a new flavour, Lime, Mott's has added a third lid colour, green.

This makes perfect sense. Limes are green and consumers should make the association between the colour and the flavour.
