yes I've done it for a science project
It will turn either blue or green, both a hue of blue. The reason of this is that Red Cabbage Juice is an indicator, which is used to see wether an object or chemical is an acid or a base. If the object is an acid it will turn a hue of pink, and if it is a base, it will turn a hue of blue. Which is why a base mixed with Red Cabbage Juice will turn green.

Both of these can be used as an acid-base indicator. The juice from red cabbage will turn different colours over a wide range of pH, from pH 2 (very acidic) to pH 13 (very basic). Red beet will be blue or red depending if it's in acid or base.

Alkalis turn red cabbage juice blue/green/yellow.
Red cabbage can be used as a pH indicator for a wide range of pH levels, showing different colors depending on the acidity or alkalinity of a substance. Similarly, beets can also be used as a pH indicator, turning different colors in acidic or basic solutions.
Red cabbage or beetroot juice will do the job.
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.
Red cabbage is often used in the chemical industry as a natural pH indicator due to its color-changing properties. It can be used to determine the acidity or alkalinity of a solution by observing the color change of the cabbage juice when mixed with the solution.
Examples of substances that can be used in an indicator test and change color include red beet juice, turmeric, blueberries, and purple grape juice. These substances contain natural pH-sensitive pigments that react to acid or base solutions, resulting in color changes that can be used to determine pH levels.
Red cabbage is one of many varieties of cabbage grown in temperate regions worldwide. Its juice contains the pigment cyanidin, which is used as a homemade indicator of acids and alkalies because it turns the purple colored juice pink when an acid is added and blue when mixed with an alkali (or colorless in a strong alkali solution).
Red Cabbage and Beetroot can be used but what else?
