The maker of V energy drinks and the Coca-Cola Company are locked in a fierce legal battle over who can own the colour green.

Frucor Beverages' attempt to register the shade Pantone 376C is now heading to the Federal Court after Coca-Cola successfully blocked its application to trademark the colour used on the packaging of its V drinks.

Frucor's application to IP Australia, first made in 2012, would have stopped other companies using the colour on other energy drinks.

Coca-Cola objected on the grounds that Pantone 376C did not distinguish V because other soft drinks already used similar colours, including its own "Green Storm" variety of Mother energy drink.
