Piet Mondrian Tableau No. IV; Lozenge Composition with Red, Gray, Blue, Yellow, and Black

This abstract, geometric painting has been tipped on one corner to create a diamond form rather than a square. The surface of the canvas is crisscrossed by an irregular grid of black lines running vertically and horizontally like offset ladders. The black lines create squares and rectangles of different sizes, and the width of the lines vary slightly. One complete square sits at the center of the composition and is painted white. Other rectangles are incomplete, their corners sliced by the edge of the canvas, and each is a different shade of white with hints of pale blue and gray. The black grid creates triangular forms where it meets the angled edge of the canvas in some places, and some of these are filled with flat areas of color. A tomato-red triangle is placed to the left of the top center point, and a vibrant yellow triangle is to the left of the lower center point. A black triangle is next to it at the bottom center, and a cobalt-blue triangle is situated just below the right point. The painting is signed with the artist’s initials at the lower center: “PM.”
