The Brits won the battle so decisively that they pushed on from Bladensburg and burned Washington DC., including the building that we call the White House today.
The White House was already white, but people didn't call it that. After their victory at Bladensburg, the British burned DC. Soot everywhere!
After the US rebuilt the city, the building was shining white. People started calling it the White House.

The US side had a few Black soldiers too! They received a similar promise of freedom. But the Black US soldiers were disappointed in the skill and resolve of some of their white peers. Charles Ball said (in 1814 language), "Bro! Why are y'all running away? We're fighting for our freedom and our country! I thought you were a militia? Pshh! Soft!"
