The solar cell module of color and taste evaluation method dark color piece

摘要

PROBLEM TO BE SOLVED: To provide a color taste evaluation method capable of objectively evaluating, in accordance with an embodiment, the color taste actually felt by a consumer when a dark-color sheet having a dark-color appearance is used outdoors.SOLUTION: In the color taste evaluation method of a dark-color sheet, a first process of measuring a first color coordinate as a CIE-based color coordinate by a standard light source D65 of an evaluation target sheet is performed, and a second process of measuring a second color coordinate as a CIE-based color coordinate by a standard light source A of the evaluation target sheet is performed. The evaluation target sheet in which both of the first color coordinate and the second color coordinate are within a previously defined reference range is determined to be preferable.SELECTED DRAWING: Figure 2
