Synthesia Talk

Hello. I just discovered about the colors.xml file and modding synthesia, but from looking through the colors file, I missed an option to change the color of the actual falling notes themselves. Is this an option, or a possibility? I would like to have more options than the 6 ones that exist by default. That way I can customise the theme of my youtube videos to match the theme of the song I'm uploading more consistently. Is this possible?

Thanks in advance,

Ruben
