Highlight the played notes in the piano roll

[bytad]

I'm using FL Studio to practice my piano playing, but it is hard for me to tell if I'm hitting the right notes, because the color of the pressed notes is too similar to the regular color of the grid (see the picture attached).

How can I change the color of the pressed notes to make it more apparent ? Changing the color of the grid itself doesn't help.

Thanks in advance.
