The pattern with the green and orange chevron pattern is a prime representation of a geometric pattern making it look very clean. It is very easy to tell that pattern is geometric because of it’s inorganic shape and lines. The contrast between the color in the pattern with the green and orange chevron pattern is more geometric in the sense that it is more man made.  Additionally, it has more of a symmetrical feeling because of the unnatural lines created.  They are natural because they could not happen through a natural event. There are also less irregularities and clear cut shapes something that can only be human made. The type of cuts matched with he color gives this pattern a natural 3D feeling. In contrast the image with spheres, could still  be considered geometric but what makes them feel organic is the irregularity between the sizes of the spheres. This is because many of the times many things are really irregular in size just like that.  Furthermore, the spheres have a strong contrast between black and white and this allows the pattern to look like it has a shadow reflecting of off it. This gives it more of a natural feeling because light reflecting off of things is a natural event. This in is key in the pattern because reflection does not happen very often specially in inorganic objects or patterns.
