Problem with overlapping materials

Hi, Im new to Cinema 4d and I was trying to make a logo 3d. So I imported the 2d logo vector from illustrator (made it outline) and starting extruding. After doing the whole logo I added colors to it (simple materials and selecting colors mannually)
When i pre rendered it with the materials applied i saw that the colors were trying to overlap because some extrudes are "at the same level". Is there anyway that I can tell cinema 4d to predominate the color according to the objects order in my objects panel? I already tried to add each object to one layer and/or check the hierarquical box in the extrudes, but nothing changed and I don't even know what are this functions for.
I didn't want to do this whole logo again because it was freaking difficult, there's a lot of objects.
Please, i think that there must be a way to tell c4d to don't conflict this two or three colors that are trying to overlap.
Thank you for the attention

Extrudes have the same rules as in AI etc. solid inside one spline then hole after it crosses two splines (solid after an odd number of splines, hole after even number of splines) But the splines have to be connected for that to work, either with Mesh/Conversions/Connect or Connect and Delete (which was Functions/Connect in older versions) or using the Connect object.
