The truth about red Skittles

When it comes to sweets, everyone has their favourite flavour - so it's disappointing when you open a packet to find there are only a few of your preferred colour.

But it's not just a case of bad luck, a tooth-achingly sweet investigation has found.

A team of sweetie fans ate their way through dozens of packets of popular confectionery, and have revealed how many of each colour you get on average when you buy certain treats.

And the proportion of each flavour is far from equal for some of the most famous sweet brands.

The team, from UK kitchen company CDA, analysed dozens of sweet packets including Skittles, Wine Gums, Fruit Pastilles, Gold Bears and Starburst.

They then worked out how many of each colour you get in a packet on average based on the packs they had munched their way through.

Starburst was found to have the most equal proportion of each colour in a packet, followed by Gold Bears - great news for those who like every flavour.

But other brands have much more of one colour than the others.

You're in luck if your favourites are green Fruit Pastilles and red Wine Gums as these are the most common colours for those brands, on average.

But otherwise, you may have to just hope that the packet you buy bucks the trend uncovered by the research.
