Color hue matching (with saturation balance) performed with LEDs in low energy mode by 3 subjects. Lightness by matching real daylight spectrum. Thanks to E. and J..

CIECAM02 color data calculated by Behrens ("Magnetkern").

WolframAlpha has a query interface to approximate spectral colors in sRGB.
