From August, M&Ms will have a new seventh colour, and an internet vote will decide which of three choices will get the go ahead.

Sweets bosses reckon purple, pink and aqua are the colour of M&Ms that people would most like to add to the green, blue, yellow, brown and orange sweets already in the bags.

Second chance for purple

For purple it's another chance to make the grade, because it finished second behind blue when that colour replaced tan in 1995.

That was the second time the colours had been changed since M&Ms were created in 1941. Eight years later tan was brought in instead of violet, before it was replaced by blue.

The sweets manufacturer has put up adverts in 78 countries asking people to vote on the M&Ms website between 6 March and 31 May.
