I started looking up colors for Paz and was able to find some of the colors that were provided in the paint reference. I also started to find some well-lit references of the costume.
Here is some of what I could find:


Aside from these, the best lighting I could find was the Hot Toys ad photos. From these references, it definitely looks like the jetpack has a bit more of an orange hue to it.

I hit a few stores looking for spray paint to color match.
Dark Blue (Primary Armor):


Krylon Satin Iris seems too bright. The Satin Oxford Blue looks more "in the ballpark".


Rustoleum Ink Blue looks promising too. Midnight Blue looked good for a while, but I'm thinking too dark now.
-----------------------------------------------------------------------------
Light Blue (Cheeks and Right Hand):

Krylon Satin Rolling Surf looks spot-on.

Rustoleum Maui Blue looks like it could be good with enough black wash.

Brown (Left Hand and Right Gauntlet)

I've used Rustoleum Kona Brown on my custom kit, so when I first looked at the gauntlet, that shade immediately jumped out at me.

Yellow (Armor)
"Oranger" Yellow (Jetpack)



The Rustoleum Tuscan Sun and Krylon Satin Spiced Amber or two very different shades. Fortunately I think the Tuscan Sun works for the armor bits, while the Amber works for the jetpack. I also like some of the other Rustoleum shades, but I feel like a LOT of weathering would be needed to match the darker/duller color.
So, in summary, I'm thinking the following for my Paz:
Light Blue: Krylon Satin Rolling Surf
Brown: Rustoleum Kona Brown
Armor Yellow: Rustoleum Tuscan Sun
Jetpack Yellow: Krylon Satin Spiced Amber
Exposed Metal: Rustoleum Metallic Silver
In anyone's opinion, what would be the best dark blue?
