Hello...Im moving from 2.0 to 3.0

I have a doubt about the List component...

Back in 2.0 to change some colors of a List Component in this case named my_list i could do the following:

my_list.backgroundColor = 0x469EE6;
my_list.color = 0xFFFFFF;
my_list.selectionColor = 0x000000;
my_list.textSelectedColor = 0xFFFFFF;
my_list.rollOverColor = 0x97A3B3;
Any ideas on how this could be easily done in 3.0 ?

Thanx in advance!
