Darker Shadows accentuate a blue

Here, once the sun has past in the evening, the driveway picks up more of the blues of the rooftop and facade. This is of course because blue light has a longer wavelength than red light - and why shadows are typically more blue than red, like the seabed apears mostly blue and not red. The blue navy tone of the house is quite obvious in full sun but here, it seems to match the driveway almost.
