A simple misstake cost millions

Lego uses about 50 different colors and when an employee in Billund changed a color tube one day in 2015 to grey a misstake was made. The tube was mislabeled with light grey instead of dark grey. Because of this misstake Lego had to repack 129 000 boxes at the factories in Czech and Hungary with a lost of $ 1.6 million.
