About this design

A field of stacked squares and rectangles in sky blue, navy, coral red, pink, purple and mustard yellow, with soft shadows that give the blocks a layered, sculptural feel. Nested square frames in light blue, cream and salmon hide the three finder squares, each with a small colored block at its center. Dark navy and light cyan blocks carry the modules across the middle, while warm yellow and pink fields frame them. Strong contrast between the deep navy and pale cyan keeps the pattern clear, and a few rounded red and yellow shapes break up the grid.
