“…Due to the transparency and characteristic absorption of the yellow jadeite, the testing backgrounds and light source would make a significant influence on the color. In our previous study, we have discussed the impact of the different light sources on jadeite and concluded that the standard D65 light source is suitable for color grading compared with A and CWF [8]. So, in this paper, the Munsell neutral value scales (N0.5, N1, N1.5, N2, N2.5, N3, N3.5, N4, N4.5, N5, N5.5, N6, N6.5, N7, N7.5, N8, N8.5, N9, N9.5) were used as the backgrounds for 33 yellow jadeite color measurements.…”
