a different kind of blue

[Dilettante]

Прошу помощи. У кого есть свободная минута, объясните, пожалуйста: как понять выражение "Different Kind of Blue"? Контекст - песня Gay Dad с таким же названием.

when I woke up dreaming
everything seemed free
scene was fascination
just rolling on

if you knew her like I do
you would say the same thing too
me and you
we make a different kind of blue

leave the window open
something's in the room
I could hear you whisper
just come on home

but if you knew her like I do
you would say the same thing too
me and you
we make a different kind of blue

it's a boy thing
like a girl thing
she makes my head sing
it's the real thing

but if you knew her like I do
you would feel the same way I do
me and you
we make a different kind of blue

it's a boy thing
like a girl thing
she makes my head sing
it's the real thing

Одноименная песня есть и у U2. Но они, кажется, пели о другом.
P.S. Если вопрос покажется смешным, не обессудьте: учить язык хочется не только по учебникам.
