Decorating question: what color shag should I go with (details, and free prize inside)

I lied. Just details.

Here is my room.

photo 5 (my coffee table)

The chair and the Madonna print (on my wall) are orange. I have a lot of green accents pieces (pillow, photos in coffee table, candles), but, I could change that.

My g/f thinks that I should go with a teal shag (oh, the horror), to go with the orange and teal pillow. We both admit, though, that it may be too much and that I will get sick of it.

I am thinking this color (Spring Beauty). It is a light sage.

There is always neutral, but, I really don’t want to have to go with that.

Suggestions?
