The fol­low­ing image is an exam­ple of a SEPIA, or “MONOCHROMATIC” (Using only one color) image, that has been cre­ated from a black & white illustration.

This is a tuto­r­ial that I really liked, because it helped me to under­stand the under­ly­ing process used in the Luck­adaisy char­ac­ters.  It is a sim­i­lar process to my own, though the artist has added some excel­lent points, a unique per­spec­tive, and a truly beau­ti­ful way of pre­sent­ing the infor­ma­tion in the tutorial.
