Red squares are symbols of stability and safety. These are 4X4 squares, each one contains 4 squares inside. The size of the squares are 40X40 cm.
There is two different paintings, one is framed, the other is not. The not framed one has dark green contour lines.
All the lines are exactly the same size, but it looks like some are smaller, others are bigger. Or some looks like rotated a bit.
