chlorophyll
Boiling water can help remove water-soluble pigments like chlorophyll in green vegetables or anthocyanins in red cabbage. These pigments are sensitive to heat and may leach out into the water during boiling, resulting in faded color in the food.
When you water leaves with colored water, the pigments in the leaves may absorb some of the color from the water, leading to a change in leaf color. This process is similar to how plants naturally absorb nutrients and water from the soil through their roots.

The leaf was placed in boiling water twice to ensure that it undergoes complete cell breakdown and to extract chlorophyll effectively. The first boiling helps to kill the leaf and break down the cell walls, making it easier for the chlorophyll to be released. The second boiling often follows immersion in alcohol, which helps to remove pigments and allows for clearer observation of the chlorophyll's presence when tested with iodine. This process is commonly used in experiments to demonstrate photosynthesis and the presence of starch in leaves.
Water-soluble pigments in leaves would be less adaptive because they could easily leach out during rain or when the plant is exposed to water, leading to a loss of color and potentially important functions such as photosynthesis and UV protection. Additionally, such pigments would not effectively absorb light in the same way that chlorophyll does, which is crucial for energy capture. Instead, plants have evolved to use fat-soluble pigments that remain stable and functional within the leaf structure.

It is not the teabag that colours the water but the tea leaves which are inside the bag, They contain various chemicals and some of these dissolve in water giving it the characteristic flavour and colour of tea.

Tea leaves go in boiling water to turn black.

Boiling water at high temperatures removes any pathogens or disease-causing bacteria present in the water, making it safe to cook with or drink.
Actually you don't use "boiling" water, You are supposed to use water that has just quit boiling. The idea is that boiling will damage the leaves (tea is tea leaves) But the water should be just that hot to release the flavour properly and the tea should be allowed to steep for a few minutes and allow the leaves to release all their different flavours naturally with out stirring our damaging the leaves. If it is done properly you get a very nice effect that I am unable to taste, so I use boiling water and stir my tea as I am impatient and can't tell the difference.
