２６号公報）。Heretofore, regarding a method for predicting the make-up skin color when a cosmetic is applied to an arbitrary object to be coated, a method of applying a make-up applied to a smooth measuring plate to a predetermined thickness in advance. The reflectance of the paint film was measured using a spectrophotometer,
There has been proposed a method of predicting the reflectance when a cosmetic film is formed on an arbitrary object (Japanese Patent Publication No. 1-477).
No. 26).

ことができないという問題がある。[0005] However, in this method, it is necessary to know the thickness of the cosmetic coating film when estimating the makeup skin color. Further, when predicting the make-up skin color by this method, it is necessary to correct the internal reflection and the specular reflection derived from the illumination condition or the light receiving condition of the spectrophotometer. For this reason, this method has a problem that the makeup skin color cannot be easily predicted.

観的評価に至っては行なわれていない。[0006] Further, a method for objectively evaluating the coloring power of makeup cosmetics and a method for evaluating the degree of natural feeling after makeup have not been known so far. For this reason, at the time of developing cosmetics and on the production line, color management is performed to determine whether or not a predetermined application color of the product has been obtained. Also, when the cosmetic is applied to a predetermined bare skin color, Although it is anticipated, it is difficult to predict the makeup skin color when an unspecified user having various bare skin colors applies the cosmetic, and when the unspecified user applies the makeup. No objective evaluation of the natural feeling of makeup skin color has been performed.

For example, when predicting the makeup skin color when a foundation is used as a makeup cosmetic, the application color of the foundation is usually adjusted to the range of the bare skin color of the face. It is preferable to use a bare skin color and its surrounding color. More specifically, hues of 5.00R to 10.00R and 0.00YR, which are the range of the bare skin color of the Munsell color system and its surroundings,

とを見出した。As shown by the solid line in FIG. 1, the present inventor has found that the colorimetric value before applying the makeup cosmetic and the colorimetric value after applying the cosmetic have a linear relationship. Furthermore, the present inventor has found that this formula can be considered as a coloring line, which represents the coloring properties of the cosmetic such as the coloring power and the coating color of the cosmetic.

くなるからである。That is, in the regression line (Equation 1), the reciprocal a of the slope is an index of the coloring power of the makeup cosmetic. This is because the greater the coloring power of the cosmetic, the greater the effect of bringing the makeup skin color of the object having a predetermined bare skin color closer to the application color unique to the cosmetic, and the smaller the slope of the regression line of (Equation 1) becomes. It is.

[Colorimetric value before applying makeup cosmetics] at the intersection with x)
(V 0 in the figure) is considered to be an application color unique to makeup cosmetics. This is because, when the application color, which is the unique color of the cosmetic, is the same as the skin color of the object on which the cosmetic coating film is formed, the makeup skin color is the same as the skin color. And the straight line y = x indicating that the makeup skin color is equal to the makeup skin color (that is, the colorimetric value before applying the makeup) is considered to be the application color unique to the makeup.

法として、化粧料の選択方法を提供する。The above-described method for estimating makeup skin and the method for simulating makeup according to the present invention enable a user of makeup cosmetics to easily predict the condition after makeup. Therefore, for example, after a makeup cosmetics user predicts the state after makeup for some cosmetics, the determination of which cosmetics is optimal for oneself depends on individual subjective criteria. Entrusted. For this reason, when the makeup skin color desired by the makeup cosmetics user and the actual bare skin color are considerably different, the makeup selected by the makeup cosmetics user has an unnatural finish. There are cases. In view of the above, the present invention provides a method for selecting a cosmetic as a method for objectively determining a cosmetic having an excellent natural feeling.

にする化粧料として選択する。According to the method for selecting a cosmetic of the present invention, the natural feeling of the makeup skin becomes excellent when the distance in the color space between the skin color of the object to be applied and the makeup skin color is small. This is based on the finding that when the distance is large, the unnatural feeling increases. Therefore, in the method for selecting a cosmetic of the present invention, for each of a plurality of cosmetics having different colors, the cosmetic skin color is predicted according to the above-described method for predicting the cosmetic skin color of the present invention, and the predicted value and Then, the distance in the color space from the colorimetric value before applying the cosmetic is calculated, and the cosmetic having the smallest calculation result is selected as the cosmetic that maximizes the natural feeling of the makeup skin color.

For example, in the uniform color space of the L * a * b * color system, if the intervals between numerical values are equal in any direction of the three coordinate axes, the distances are visually equal.
No special normalization is required for calculating the distance in the color space of two colors. Therefore, the point (a * 1 , b * 1 ) and the point (a *
2 , b * 2 ) can be obtained by the following equation.

例えば、次式で得ることができる。On the other hand, in the Munsell color system, the relationship between the interval between numerical values and the visual distance is proportional on the same axis, but different axes have different proportionality coefficients, so standardization is required. Specifically, a distance of about 4 in the hue H direction sensuously matches a distance of about 1 in the lightness V direction. Therefore, the distance between the point (H 1 , V 1 ) and the point (H 2 , V 2 ) is
For example, it can be obtained by the following equation.
