WebThe CIE recommends using linear interpolation of the component SPDs, S 0, S 1, and S 2 if the application requires greater precision, but there is a proposal to use spline interpolation instead. Using the standard 2° observer, the CIE 1931 color space chromaticity coordinates of D65 are WebJan 1, 2015 · Lines of equal tint run approximately parallel to the line of dominant wavelength 470 nm (467.6 and 464.7 nm, respectively, for the 1931 and 1964 CIE standard observers) in the chromaticity diagram. Figure 1 shows the line of dominant wavelength 470 nm and also two lines of iso-whiteness according to the CIE whiteness equation.
