I'm not sure why I'm jumping into this; believe me, I'm not making fun of anyone's point of view... I'm just trying to to point out something that should be inherently obvious.
That is: you can't possibly expect to match the color of a 3D object in the real world with an arbitrary Pantone color. The most you can *aspire* to match is the *hue* of a reference color. Any object that contains highlights and shadows will vary from the reference color; otherwise, it would look like a cardboard cutout.

For reference, that's a Pantone 484 cardboard cutout.
You might be able to get a flat object - like a logo, under flat light - to pretty much match a reference. But if it's interacting with the world, and light reflecting off of other objects, all sorts of other colors and shades are going to enter into the picture, and that's almost always part of what you're trying to capture in any kind of photography or cinematography.
I know, it's true; clients are always going to throw a Pantone reference at you for color matching. But Pantone comes from a different world: the world of print or manufacturing. It's meant to define an utterly static color value; it has next to nothing to do with how that color might look once it gets out into the world.
That Coke bottle is going to look entirely different - it *has* to - at high noon on a Cape Cod beach, than it will the same night at a candlelit bar.
I work a lot with 3D CGI, and rendering techniques such as raydiosity and global illumination, which deal specifically with light coming from all directions, bouncing off different-colored objects, and contributing traces of those colors to the scene and the objects your attention is focused on. They greatly improve realism, because they mimic the incredibly complex and glorious way light bathes everything all the time in the real world.
So just what am I babbling about here?
I guess I just can't imagine pointing a camera at something, and complaining that the camera is broken if what you get isn't identical to what you would see if you just held up a mirror. For goodness sake, use a grey, white or color reference, and correct to match the values that are most important to you. There are effective ways of doing it other than masking everything but a specific object.
There's a reason a copy of Resolve comes with every BMCC. They're both astonishing tools. If you really think the camera is "broken", send it back - it's still under warranty. Please.
And for God's sake, please correct the spelling of "phase". It's like an ice pick in my eyeballs.
Thanks.
