Concept of CIE L a B space: the hair color treated by the method shows the trend of color transition during the experiment, and the color space is represented by L.a.b.values and is perpendicular to each other, and the equal distance is approximate to equal color difference in the color space. Wherein L represents luminance; a represents the red/green coordinate axis; the b values represent the yellow/blue coordinate axes. An increase indicates a lightening of the hair color; an increase indicates that the color development is moving in the red direction; an increase in b indicates that the color development is moving in the yellow direction. The tolerance formula aspect adopts a CMC tolerance formula.

CMC tolerance formula: CMC tolerance methods use ellipses as a range of visual versus chromatic aberration, and thus CMC versus chromatic aberration representation methods are considered more accurate and reasonable in industry than CIELAB representation methods.

CMC tolerance formula:

ΔE _CMC ＝[(ΔL*/IS _L ) ² +(ΔC _ab */cSc) ² +(ΔH _ab */S _H ) ² ] ^1/2

the constants l: c in the formula are set to 2:1 according to the kind of hair similar to the textile industry.

The following conclusions can be drawn according to the actual situation and the numerical calculation result of the chromatic aberration calculation formula:

delta E is between 0 and 1, and chromatic aberration is indistinguishable to naked eyes;

delta E is between 1 and 2, which is slightly noticeable to the naked eye;

the delta E is between 2 and 3, so that the chromatic aberration among substances can be slightly clearly distinguished;

the delta E is between 3.5 and 5, and the color difference is very obvious;

delta E above 5, then a very large color difference, even two colors, appears.

The comparison of the results is shown in FIG. 1.

While the invention has been described with reference to the preferred embodiments, it is not limited thereto, and various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
