Select items in Live Paint groups
Use the Live Paint Selection tool 
to select
individual faces and edges in a Live Paint group. Use the Selection
tool 
to
select the entire Live Paint group, and the Direct Selection tool 
to
select paths inside a Live Paint group. When you’re working in a
complex document, you can isolate a Live Paint group so that it
is easy to select the exact face or edge you want.
Choose a selection tool depending on
what you want to affect in a Live Paint group. For instance, use
the Live Paint Selection tool to apply different gradients across
different faces in a Live Paint group, and use the Selection tool
to apply the same gradient across the entire Live Paint group.
Select faces and edges
