How to add color to released components at the product level?

Hello-

We have some assemblies that we imported from SolidWorks to CATIA 3DX and all the items came in with the same color. It is important for the components to have the right color and the problem is that they are released and their is hundreds of parts. I am wondering if there is a way to change their color at the product assembly level which is in-work and not released. 

Thanks
