How can I fix the ball from going through the brick at start of game?
The pink ball is going through brick boundary at beginning of game, after it returns and hits the paddle it detects brick boundary.

movement update for ball and brick change color update when brick is hit

brick update if statement, I added a print statment to see how many times it counts brick as getting hit at start of game and it returns the value 1 2 as soon as it hits the brick.
if self.hit_brick(pos):
self.y = 1
color1 = color1 + 1
print(color1)

brick.draw()

At start of game ball should bounce off of pink brick but goes straight through and bounces back.
