Blue And Orange Martini?

My company is hosting a martini bar at an event and we want to have a martini
with our company colours.  

Our colours are blue, orange, and white.

Is there a way we could make a blue/orange martini?  How hard would it be?  
Any ideas off the top of your head?

One suggestion was:

2 oz. Vodka
1 oz. Blue curacao
1 oz. Cointreau

Cheers!
