Blue pill, red pill, choose now
I think when they reference the blue pill red pill scene in the matrix Kendrick means that you can take the red pill, and like in the movie you stay in the world as you know it, doing what you were doing before (in this case dealing drugs) or take the blue pill and like in the movie, break out of the cycle. The whole song seems like Q wanting to leave that life but staying in it for supporting his family.
He ends his verses with Birds and the Bees because all of the drug shit is natural where he live and grew up. Hence, he’s going to keep doing it. But Kendrick’s verse is like the voice in the darkness telling him to break out of it, and this line is him offering the choice- break free and prosper or stay in this life and go to jail like so many black males in America and have his daughter grow up fatherless. It’s a catch 22.
It also paints a color metaphor for the last line, “And the block hot, you keep runnin', cop say freeze”, and red is for hot as freeze is to blue.
