We were so happy to continue the tradition of purpling this year with Lassonde WeekZero!
There are many different origin stories behind the idea of purpling, but the most popular one is that British Royal Navy Engineers would wear a purple band around their arm to distinguish themselves from other officers during World War II.
The sweat and brine from the harsh conditions they were working in would cause the dye of the purple armband to stain their skin. Every year, the Lassonde Engineering Society hosts a Purpling Party for all WeekZero participants in order to dye themselves purple and continue that tradition to remember the contributions of engineers to the world.
