As you've likely found out, CN remains its stupid gold color despite the shader you use thus reducing you to a few shaders that match it.
Personally I use default with Osiris armor but the gold of the Osiris armor is more metallic looking than the bronze/gold of CN.

It's very, very hard to find Shaders that compliment a lot of the Hunter armours. At the moment I'm using Thunder Devil but I hoping to find a better option.
