Red cabbage is rich in a pigment called Cyanidin, which is one of several anthocyanidin pigments found in plants. Due to it's chemical structure, the molecule is easily able to add and remove -OH ions from itself. When an -OH is added to the molecule, the electronic configuration of the whole molecule changes. The electrons actually interact with the light and produce colors. Because of this, the color of the molecule is directly tied to the electronic configuration and changes when the -OH is added or removed. Remember, acids remove -OH ions and bases add -OH ions, which is why this compound serves as an indicator. So in the presence of a base, the OH is added to the cyanidin molecule, the electronic configuration changes, which changes the way it interacts with light and makes the molecule turn blue. An acid removes the OH, and it turns red. See the source links for more complete info.

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 baking soda mixed with Red Cabbage Juice will turn blue or green.
