Leaded Glass Doors- how can I refresh them?

How would I go about refreshing the lead portion of this style door? Some of the gold is rubbed off of the lower right door portion. Is this even fixable? Can I change the color to black or is that ridiculously unheard of? (our detailing is black in our kitchen, no gold anywhere) Help. I'm clearly uneducated in leaded glass but would like to learn. Thank you in advance.
