The present invention provides a coloring solution for zirconia, which, when used on zirconia before firing of the zirconia, causes the zirconia to exhibit only a slight color difference before and after the firing and thus enables accurate prediction of the post-firing color tone of the zirconia. The present invention relates to a coloring solution for zirconia, comprising: a coloring agent (A) that is decolorized after firing of zirconia; and a metal ion solution (B), wherein, when zirconia is colored with the coloring solution and then subjected to firing, the color difference of the zirconia before and after the firing satisfies ΔL*≤5.8, Δa*≤2.4, and Δb*≤4.3.
