I know that size, color, proximity, etc. are the building blocks of visual hierarchy but I'm wondering, which properties have priority over others?
For example in this video it is shown that when you add color to a bunch of circles the eye is drawn to it. However in that same example there is a circle with bigger proportions than the others. So, why wouldn't the eye be taken to the size first and then the color? Does color have a higher priority than size?
Also, I don't really agree with his demonstration of visual hierarchy on a previous version of the apple site. I think the image is visually more powerful than the big-sized bold headline. What do you think? Do images have a higher priority in the visual hierarchy than other properties?
