The Fotospeed Palette Toning Kit has pushed open the boundaries of metallic toning to allow an array of vibrant hues to be created from a single kit.
The kit is comprised of four toners: Titanium Yellow, Vanadium Yellow, Red and Blue. Within each color, many hues are obtainable.
The variety is immense simply by adjusting time and combinations. Like the three primary colors (yellow, magenta and cyan), placing the print to be toned into each solution for varying times creates a color mix in the final image.
