In our company we use 2 colors for our machines; red and yellow. When we insert parts (or assemblies) into an assembly the color changes. The appearance seems a lot darker. For example, our yellow part turns to brown. The appearance (RGB/transparency/reflectivity etc.) remains the same.

How is it possible that our appearances changes suddenly?

Could it be the emission of our parts/assemblies?

If the problem is the emission, then the emission of a part (50%) seems to be set back to 0% in the assembly. I found out that our emission of all parts and assemblies should be set to 50%. I can change the emission in a (default) part but not in an assembly. Is there a way to set the default emission value to 50%?

Thanks in advance!
