How does colored water affect a white flower?

I'm taking Biology in college right now...this is what I gather.

Dye in the water doesn't harm the plant (in most cases). the water is absorbed through the roots of the plant, which travel to the leaves/petals, there they are then evaporated while producing energy process of photosynthesis...water is attracted to each other -aka cohension, water molecules are attracted to each other b/c of positive and negative ions. All being said, the water evaporates while the dye remains in the plant.
