This is my Broadway Boogie Woogie that i made and as you can see on the right i made it by making different brush versions. To get the shapes you just need to make like six different little suares of whatver colors matches with the boogie woogie like yellow,grey, red and blue. You make them into a group and drag that group to the brush panel. I Made the big red squares normally by bringing that square icon to the right and making blue, red, yellow and grey versions on top of the reds as well as blue squares.
