"Aqueous Color Iro-no-Moto" is a paint additive that has been adjusted in density so that the three primary colors "cyan", "magenta" and "yellow", which are the raw materials for Aqueous Color.  

"Aqueous Color Iro-no-Moto" does not contain a pigment (white or black) that increases the general surface hiding power, so it can not be used in the same way as other hobby paints as a single substance, but the color tone of the existing color can be fine-tuned without muddying the mix.  Create candy paint with bright color to take advantage of high color transparency, and bright metallic color toning that was impossible with the existing color mixes.  When mixed with the appropriate clear base, it can be used as an original clear color that can be painted on clear parts.
