Blueprint is definitely metallic, great colour though, was looking for a blueprint XR8 for a while. ('settled' for venom red in the end as the condition of the car was too good to pass up. At least it's a good match for my RS though!)
BLUEPRINT TE50
There's a solid Ford blue from the seventies called True blue. Maybe a bit light for what you're after?
TRUE BLUE XY GT
Ford Bionic blue is pretty close to the colour on the MK2 Escort you pictured.
It's a solid blue too & was available on the B series falcons.
BIONIC BLUE
Cheers, Jason.
