Format bars in P3e

I am new of P3e.
I faced the first problem, because I need to format bars (Color) in different ways.

In P3 was easy having two main possibilities:
- select the bars and then apply a format (colors, etc..);
- apply a format to a set of bars in function of an activity code value.

It is possible to do the same in P3e, and how?

Thanks for the help.
