That's color-shifted a little I think, as the trademark Wilier color was more like copper than bronze. Plus, this is a cromovelato paint job: transparent lacquer (copper colored) over full chrome plating. Not something to try if you have a budget. You can get a similar (but not quite) effect by spraying a sliver metallic base coat and a transparent top coat, this was a practice of many British bike painters (called "flamboyant" paint in that case) as well as US hot-rod customizers (Kandy-Kolor). For variety, this was sometimes used with a gold metallic or white base coat.
The lac-over-chrome is particularly fragile as the paint itself isn't very durable and adhesion of any paint on chrome is poor.
