Super Dee Dooper

Why is it that the two times the (Indianapolis) Colts get into the Super Bowl, the Super Bowl logo is primarily orange? 

Look at all the lovely logos the NFL has had in the past (go on, look!) - and the two that are mostly orange are....Super Bowls XLI and XLIV. 

Is it the Miami connection?  The Orange Bowl?  If they are going to use Miami Dolphin colors, why not some lovely turquoise or teal or whatever color that is? 
However, I would much rather deal with orange splattered on my blue and white merchandise than watch someone else play next week.

Rock on and GO COLTS!
