I've never noticed that before. Are all the constraints dark, or just some of them? Are there any symbols in the tree in front of the dark-colored constraints? Does this happen to all of your products, or just one?
I might have found the problem: The CATIA Help files say that inconsistent constraints or over-constrained constraints will be ignored and displayed in a green/gray color. Here's what I found: Assembly Design and scroll down to the Inconsistent Or Over-constrained Assemblies section in the Managing Constraints chapter.
