Eye movement tendencies for shades, sizes, shapes, and colours I was asked this question yesterday

Which of the following statements regarding research principles in visual attention is TRUE? The eyes tend to move from:


a. Light to dark (shade) 
b. Large to small (size) 
c. Regular to irregular (shape) 
d. Unsaturated to saturated (colour) 


I answered c) (can't remember where I Googled it but found that to be the most appropriate answer). I am worried that I am incorrect and would love to canvas the opinions of others. It shouldn't matter but the above question was in the context of web .
If the question means in which of the option pairs is the second one more attention-grabbing, I would guess d.

a. Light to dark (shade) - I would say that visual attention is automatically drawn to bright areas in the visual field, so, exactly the opposite.

b. Large to small (size) - exactly the opposite again, bigger objects would be more attention-grabbing

c. Regular to irregular (shape) - This one is a tricky one because there is evidence for both. But from the options given in the other answers, I assume the question is about stimulus-driven attention, and there, attention would spontaneously go to the gestalts in the visual field (here's a recent example).  

d. Unsaturated to saturated (colour) - And voila, I would say that the more saturated is the more attention-grabbing of the two. (see here for a randomly googled reference, it also supports not choosing answer a)
