color vs. position
It’s funny how trained humans become at certain tasks. I recently upgraded to the latest iTunes release for Macs, and the iTunes logo has now changed from green to blue. My mind and hand are trained to know exactly where in the dock the icon is, but now that’s it’s blue it takes me a little longer to get it open. My eye is still trained to look for the green logo, and it keeps initially skipping over the blue logo. So, the question is, is color a more powerful UI (User Interface) factor than position? They are both obviously important, but which has a more lasting impact on the user? Which change would a user adapt to more quickly?
