Riso Ink Colors

Color palettes were extracted from Riso Ink Colors

Risograph inks are soy-based and do not conform exactly to any color standards. The listings below are approximates for reference only. Additionally, Riso inks are also slightly transparent and allow for variations in overprint and based on the color of paper they are printed on.

Functions

riso_names()

riso_color("indigo")

hex_transparacy("#484D7A", percent=0.5)

riso_color("indigo", alpha=0.5)

show_colors(riso_color("indigo"), "Indigo")
