Change note colour on play back

Hi,
I would like to change the note colour on playback it is blue at this moment , my vision is not as good, and when I follow the notes as it is playing I loose the note because it hard for me to see it. I would like to change to RED maybe.

Please can you help thanks sorry for any inconvenience.

Kind Regards,
M.N.Wali.
