The human vision system adjusts cone sensitivity of each channel to achieve chromatic adaptation. Similarly, the color correction of an overall color cast is done by adjusting the RGB channel gains.
Because UV light is absorbed by both these two different cells, the presence of two peaks in the dark-adapted spectral sensitivity curve measured as a whole by the ERG might be decreased under UV chromatic adaptation. The visual pigment with an [alpha]-band peaking in the UV region cannot absorb yellow light, so yellow-light adaptation caused the apparent change in the shape of the spectral-response curve.
This review also found that studies where the subject experienced mixed chromatic adaption reported a stronger effect, while studies where the subject experienced full chromatic adaptation reported a weaker but still significant relationship between SPD and brightness.
