Control colours with RGB, thats basically it.
atm theres is no way to intelligently pick a colour for your actions with set filter or set colour.
you can right click and use exspression, but this method gives you pretty random colours and if you want anything besides red youll need to multiply it by over a million.
i think you should be able to set the colour with rgb values from 0-255.
something like: set filter colour to -"25,36,255"
this would allow us to make things like: set filter colour to "lerp(0,255,('t')),lerp(0,255,('t')*2),0"
ect which would be a very usefull addition and give us real control over colours using events instead of the way its set up now.
