| We developed a fundamental technique for metamerism
        art. Under the light 1, the mixed paint 1 and the mixed
        paint 3 are aimed to be same, and the mixed paint 2 and
        the mixed paint 3 are aimed to be different. Under the
        light 2, the mixed paint 1 and the mixed paint 3 are
        aimed to be different, and the mixed paint 2 and the
        mixed paint 3 are aimed to be same. We use subtractive mixture model for the mixed paint. The proposed
        algorithm automatically finds the proper weight of each
        paint from the oil paints' database that causes the
        metameric phenomena. |
