The "Not Everything is Black and White" is pretty much what I call a direct lift from Karla Alexander, the New Cuts for New Quilts book. I bought the book for the front cover, but this project is on the back cover.

I really like her Stack the Deck series of books and different construction techniques where I can make great looking projects without having to be too fussy about my vision and precision. I've made several now based on her techniques.
One thing I learned in mine is that I used two different polka dot fabrics intersecting in the centers, again -- too fussy to bother with (one is black with white dots and the other is white with black dots). They are only 1" sashings and a simple single 50/50 black/white polka dot background of either color would have been fine.
The "Black and White and Red" is just a common jelly roll idea, inserting a square at intervals.
edit: and when I was sewing, I indeed went black strip, white strip, red square, repeat!
