How do I make the first bar pink as well?

u/sigveseb

You need to make sure you set fillStyle before you call fillRect. The canvas context is stateful like that, it remembers the active fillStyle and uses it for all subsequent fill calls until it is set to something else. The default fillStyle after reseting a canvas is black, which is why the first bar is black here :)
