PROBLEM TO BE SOLVED: To simplify setting of a specification for coloring a specific color in a specified mode, with respect to a lamination coating film configured by laminating a first base coating film 4 with a second base coating film 5.SOLUTION: A model is set such that the coating color of the lamination coating film is expressed by a color coordinate value N in the color space which varies exponentially with the coating color of the first base coating film as reference and with the coloring agent concentration X and the film thickness Y of the second base coating film as variables, and, under the condition that the color coordinate value N becomes the lower limit TL of the target color coordinate value at the lower limit of the film thickness variation range of the second base coating film 5 and the upper limit TH of the target color coordinate value at the upper limit of the film thickness variation range, the color coordinate value B1 of the first base coating film 4 and the coloring agent concentration X of the second base coating film 5 are set corresponding to the film thickness varying ratio Z of the second base coating film 5. |
