Solidworks CAD file to 3D PDF

Hi.

I'm a Technical designer and I'm new at this forum.

When i create a 3D PDF file from Solidworks, some of my apperances (surface colors) disappears/changes when i open the 3D PDF file.

Example, parts of my logo on my product, changes from black to purple??

Can i some how change the color back to black in Adobe?

Best regards,

Rakel
