I was kind of thinking the same thing that another person is here. That is the board color for Keryo Pente is a little bright. My suggestion is a neutral color such as light-blue. Althought I don't like to use this as an example, the color of the light-blue Gomoku boards at IYT would be a good color for it.
Also, there is one thing that is creating a problem for players who store their Pente and Keryo Pente games on their computers for future reference. That is in both of your Pente and Keryo Pente games, the coordinates of the board are rotated and faced the opposite direction when a player is playing the black stones like would be done when playing the black pieces in games like Chess or Checkers.
This makes sense for games where pieces are MOVED on the board like Chess and Checkers. But for games where placed pieces are not actually moved, it is not usual to have the board rotated. This is because games of that nature are generally stored in static boards and databases, regardless of which side that you are playing. So the coordinates that are shown when playing black always end up being the exact opposite of the way that we store them.
If it is not a big problem, my first suggestion would be to eliminate that rotation for Pente and Keryo Pente. Then if you feel it is necessary to be consistent, I would suggest doing the same for ALL of your games where coordinates are specified but where pieces do not move once they are placed on the board.
If you want to confirm that with a couple of other Pente players, I'm sure that Dmitri King and Erika would say the same thing.
