The Steelers only have one logo because when they originally put the steel mark on the helmets they wanted to see how it looked on the gold helmets and put it just on one side. And later that year they went to the playoffs for the first time so as good luck they decided to change the helmet to black to show the logo better and keep the one side.
The Chargers helmet colors changed in 2020 when they unveiled a new logo and uniform, featuring navy blue, gold, and white as their primary colors.
