M&M's have released a new colour mix in preparation for the Rio Olympics. The paccks will be available in peanut and chocolate and feature green, blue & yellow sweets. However you may not be able to find these in Sweden. This is because a Swedish court has ruled that the confectionery firm Mars can no longer advertise its M&M's brand with the lower case lettering "m&m". The court ruled that the logo is too similar to the single lower case "m" used by the Swedish chocolate covered peanut brand Marabou. If Mars doesn't appeal it will have to use the capital M&M logo in Sweden starting in July.
