Trying to determine correct color for touch up

[pointyskull]

I have a blue 2009 Yaris 2-door hatchback and I'm trying to find the correct color name

I've looked through a few sites and there are a couple that look very similar (Bayou Blue Pearl and Blue Metallic)

Any one have any thoughts?

thanks in advance....
