The deep blue pigment of this color used to be obtained by an impure form of cobalt arseniate or cobalt oxide. This pigment was used in stain glass creations during the Victorian Era. The name zaffre for a color has been used since the mid-1500s. It is a form of blue that is both bright, yet dark at the same time. It’s hard to describe how that is possible to be done by the same color, but that’s exactly what zaffre is.
