Why is Lattimore's jersey numbers a different color than the rest of the team??

I noticed the same thing on Jordan Howden, week 1. It could be water or sweat. Old gold is a hard color to waterproof.
This. It's all it is.

Not sure why everyone's so surprised. It's been like this ever since they switched to the Vapor Untouchable style jerseys.

Between sweat, stray water bottle sprays, and players straight dousing their heads with water to cool off, it's easy for the numbers to get wet.
