Coolant light on at start and until warm, then shuts off. 2011 outback, ok?

What is your question?

I just bought a new to me 2011 Outback (2.5i m/t) and am learning all the idiosyncrasies of this car. I noticed that the coolant light illuminates and shuts off when at temp. What throws me is that it's blue, I would think it should be red if it's too hot. Maybe it is and I just don't know. Anyone have input on this? I realize this may be a "duh" question but you don't know what you don't know.

What makes this problem better or worse?

once vehicle is warm

How long has your 2011 Subaru Outback had this problem?

no clue- car is 2 days old to me
