Hello,
I was just playing around after finishing this project and see if I was able to make some random color mixing.
It took me some time to google, re-calculate and some trials and errors but i guess it is working fine now.
Just curious what you think about it.
Probably there is still room for improvement.
Regards,
Ruud
