Okay don’t laff. Seems funny though. I think some users may not be able to see the charts. According to wiki, “Daltonism” (color blindness) 7-10% of the population have difficulty with color, mostly males. [red/green-orange/lime.green : is the commonest] The -3 months, 10 Days/Price, 10 Days/Volume charts would be tough or impossible for some to see. Wiki’s article : “Category : Articles with images not understandable by color blind users” provides some clues. I think this is why Forbes, Silicon Alley Insider, Yahoo Finance, Google Finance … and maybe even Apple’s OS UI etc, use Black and White, Blue, and Gray. Those 4 colors, lets call them that, are probably what everyone can see. This c.b. phenomenon, interestingly, exists in less than 0.4% of females. I’ve read rare females even have hyper color vision that puts them in the same category of being able to see colors like a bird or a butterfly. So when you see business websites using a very limited array of colors and tones, it’s because people get sort of aggressive or messed up if they have issues easily seeing the content, maybe more so if its intellectual in nature. And, like when did anyone ever hear someone complain about an inability to see a color or the differences between colors : never : odd too when 7-10% have Daltonism. I thought of this because when Calan was invited to TH his response was, the colors didn’t do anything for him. Otherwise, in my life time the 7 or 8 people that I’ve know and secretly followed or studied that had Daltonism proved to have certain qualities in common. Pattern recognition was one of them. I will go out on a limb and believe that throughout Art history the men who were sculptors probably were the likely ones who had trouble with color and chose form, tone and light instead. Architects too, to boot. jmho.
