An example of point randomness in action. If all the triangle "spruce trees" were the same color, you would only see a green mess which the eye would not indentify with anything in particular. Here each tree has (small) variations in both luminance and hue. This gives edges for the eye to see, and most people will think of this as a forest. It is interesting that a simple "box" distribution is better here than a bell-shaped Gaussian one. There are enough objects here that the bell-shaped distribution will often have an extreme event -- where one of the trees appears purple or yellow.
