colorspace ----------- PDF color spaces. Currently, it supports: * spot colors * mixing inks (spot and process), up to 4 * ICC based default CMYK, RGB and Gray spaces * overprinting It requires xcolor and currently only pdftex and luatex. For example, to define a spot color, just say: \definespotcolor{foo}{BarTone 555 GN}{.3, .4, .5, .6} That's all. Those docs, like the package itself, are still somewhat tentative, but the basic behaviour described here will be preserved in future versions. 2015-06-01
