Indeed, it seems there's no consensus on a fixed rule to apply for all 
cases. The example wasn't really to define a mandatory coloring, but 
just to show what I wanted to achieve by coloring beats differently :)

It was almost perfect, thanks a lot!. I just needed to make a few 
changes and add some missing time signatures. Now that I see it working 
I'm thinking that I should also add color to the corresponding

Many thanks to Aaron as well.
