In terms of etu, the new relative units of area,(in the painting) the area of one white triangle (a eutrigon*) equals the sum of the areas of the red and yellow triangles minus the area of the blue triangle. This painting provides a visual proof of a new Pythagoras-like theorem (which I call the Eutrigon Theorem) for triangles in which one angle is always 60°.
