The frontispiece of Senefelder's Manual of Lithography printed in two colors as well as black, reproducing the color printing of the Mainz Psalter, with precise registration, is considered the beginning of chromolithography. This version is, of course, a translation, with redrawn illustrations, from Senefelder's first edition published the previous year.
Historically, Senefelder's choice of reproducing the color printing in the 1457 Mainz Psalter as a way to introduce chromolithography was very appropriate since the color printing in the Mainz Psalter may be considered the beginning of color printing.
