Colors Are Different on Two Different Graphics

This one is really stumping me. 

The same image appears on two different Framemaker Documents. However, one appears grey (which is correct) and the other, black (incorrect). 

I cannot find the source file for these, so it's not as simple as importing the image. 

I have tried to adjust color in the Anchored frame and Object properties. They are the same. For Object Properties, I even right-clicked and selected "Object properties" for both. They are exactly the same. 

I tried the line fill adjustments in the Object properties toolbar. They are exactly the same. 

I tried view\color\definitions. They are exactly the same. 

Any thoughts? I know I'm doing something wrong (or not performing the right action). Thanks!
