select union with table name

Hi, I have two tables.
create table blue (
id serial primary key,
name text not null,
kill text not null
);

create table red (
id serial primary key,
name text not null,
kiss text not null
);

select blue.name from blue union select red.name from red; give me this:
name
'blabla'
'bubu'
'haha'
'kkk'

I want this:
name table_name
'blabla' blue
'bubu' blue
'haha' red
'kkk' red

Could I?
