Notes:
1. The percentage shown represents the ratio of the respective red, green, or blue channel value to the clear channel value.
2. The 465 nm input irradiance is supplied by an InGaN light-emitting diode with the following characteristics:
dominant wavelength λ
D
= 465 nm, spectral halfwidth Δλ
