When I actually had to look for color, I really noticed them more than I normally do. You see so much more when you just take the time to look for it. Its amazing how much color you find, that you normally wouldn't even pay attention to. While searching, I found a bright green bike tied up to the fence just outside. Its not really a color that I think you would normally see on a bike, but I think it works very well. The color is a very bright lime green, and as soon as I saw it, it made me think of going fast. It makes the bike seem very streamlined and flashy, so you notice it as it zooms by you on the street. Then as I was walking, I found a newspaper stand that was a very different color than all the rest that were next to it. It was a very odd purple color, it reminded me almost of purple cabbage. It just seemed to be such an odd color for that type of object. But, I guess making something an odd color like that gets us to notice it more. We look at the crazy purple one and are attracted to its weirdness, and just pass over the rest of the generic red and yellow ones. So, although it is a weird color, it works in a positive way to grab your attention.
