COLOR

I'm not exactly sure why some natural things are the color they are. But, when you think about it enough you can figure the reasoning of most man-made things. For example, construction workers use bright neon ribbon to mark trees. They are purposefully made that color because they need to be seen from far away. The bright colors are noticeable, they are attention grabbers and that is why the workers use that specific color tape. A lot of companies use bright colors to get them to buy their products because the brightly colored product will stand out on the shelves. Some man made things are made of natural materials and so the color isn't necessarily decided, like, bricks.
