A buffer absorbs or releases excess hydrogen ions, making the solution hold at a steady pH. Since red cabbage indicator makes a good pH indicator, it has a neutral pH. any amount of acids or bases added would change the pH of the red cabbage juices. If it made a good buffer, it would not make a good pH indicator.

It is important to release a liquid.
It is an acid, because Red Cabbage Juice is an indicator, and White Vinegar is an acid.
I've never heard of it changing color when it is cooled, but it does change color with pH, and can be used as an indicator for acids and bases.See the Web Links for more information about using cabbage color as a pH indicator.
Because tooth paste is a base because anything that turns a blue or green when mixed with red cabbage juice(indicator) is a base.

Nothing, but red cabbage is a simple pH indicator at home (red in acidic solutions).

Filtration
it is an indicator.
Red Cabbage and Beetroot can be used but what else?
It is important to release a liquid.
An artificial indicator is one that is chemically made and you cannot create from Natural Resources e.g. cabbage juice
anthocyanin
