I have in my notes that coordinated movement of vesicles can lead to visual changes in cell, can you explain this again a little bit?

If a cell has dozens of small vesicles each filled with pigment molecules, any one of those vesicles by itself isn't going to be detected by our eyes as "colored." But if all those vesicles come together, that part of the cell exhibits a stronger color that our eyes can detect. This happens by gathering and then dispersing those vesicles along microtubules.
