Metroworks:
The first thing you should do is go to the Surface Settings for this Surface, change the Engine Settings: to CineRender, then look at the Color setting. You could post a screen shot of that dialog box for feedback. In your attached pdf file I see only the 3D Window and the rendering. You can also try the
Match Settings... CineRender to match from Internal on the CineRender settings page.
You should add a Signature to your Profile (click the Profile button near the top of this page) with your ArchiCAD version and operating system (see mine for an example) for more accurate help in this forum.
