Soldini, Anima brutorum, 1776 (a8r; Getty)

The opening of each chapter in this book features intaglio initial letters, the colors of which vary from copy to copy. In this copy from the Getty, a blue ink is used, but in the Smithsonian’s copy, the initial letter is printed in sienna. (The plates facing this page also differ in the two copies; search “Soldini” to compare.)
