How is metalic ink or flat foil photographed so that it appears as metal?  I tried several different types of light.

All of the light parts are a silvery periwinkle or pure silver, including the markings on the feathers and outlines. There are reflective ink strokes in all of the filled areas.

I will try all ideas with instructions, that I have the means to implement.  Thank you.
