If you're 'spoofing' the light sensor, it may also result in the cabin temp being a bit warmer (or at least slower to cool to set temp) on sunny days.

This appears to happen on the Manual Temperature Control system too... When the sensor is shaded, A/C output is reduced... Probably to increase fuel mileage..
As far as certain colors of cars becoming harder to see as it gets dark, I notice my silver car at dusk or dawn becomes almost invisible once you get about 30 yards or so from it... especially if theres a little dew in the air..
