Both, however, share one problem. Outside the transmission peaks of the red and blue filters, there is little response
from the other channels. As a result, neither type can accurately represent the wavelength of narrowband sources at the
spectral extremes. In the red region, this problem has minimal impact because the apparent color to the eye is not much
dependent on wavelength. In the blue, though, the eye continues to register color change to the end of its sensitivity
range moving from blue to indigo to violet (note the secondary blue peak in the red tristimulus curve in figure 1). In
both of these filter schemes, much of the shift can be lost, the wavelength change being recognized only as blue of
fading intensity.
