Copper tarnishing and coloring

I am a student of accessory design in national school of design India. I am using thin copper plates for my project in unconventional jewelry and other accessories. My problem is that copper turn green and I have to dip it in sulfuric acid or diluted nitric acid to remove the tarnish...but if I have to make a product that is always glowing for say a year is there a way I can protect the copper sheet? please let me know as early as possible also if anyone knows the magnetic effect of copper or on copper in connection with making mobile cases in copper. I also want to know if copper can be painted or colored.(some transparent or melamine colors)
