To make Posters, Booklets and other forms of print media more interactive, interesting and engaging for the audience, the concept of Fuji colour swatches was developed.
Fuji colour swatches could be used with print media from which one can personally paint and reveal the content of the page.
This type of interactionn could be used in children's books, calenders, greeting cards and more.
They are actually sheets of paper that are impregnated with super-saturated water-based ink.
To pick up the paint, simply wet a brush (or use a water brush) and swipe it across the surface. The color that comes up is saturated and vivid.
