I think the only way is to scan (using the __key property) all the entities of the Knights model and update a set of the strings. Another way to do it, is to have a another entity:
KnightColor: pass The keyname for each "empty" entity is the color. For each Knight you put in the datastore, check if the colors are in the datastore or not, if not add the missing ones. Then you can scan this table and get the list of all colors. I am not sure if it matters but it is also going to be sorted by color as well.
