I'm not sure where the information on move option colors and features in this recent entry update came from -- Uberdude's videos or elsewhere -- but much of it is incorrect. It should be cross verified to match the information outlined in the developers own program instructions and feature list: https://github.com/featurecat/lizzie/releases. For example, best move is indicated by cyan, regardless of whether it has been explored the most. There are also circles around move options, two of which represent different types of best moves. These details can all be found in the link above.
