PixelSearch confusion

[thingy 0]

could someone help me understand the PixelSearch function.

Having read the help file, PixelSearch finds a pixel of a specified color within a defined rectangle, then stores the x,y coords in an array. My question is, what happens if there is more than 1 pixel of that color, which x,y does it find?

What if I want to find ALL instances of a certain pixel color within a defined rectangle - could I use some kind of loop and store the result(s) in an array the same size as the rectangle? Would PixelGetColor be better for this though?

That's cleared the issue for me, thanks!
