The shadows cast by trees now are not as short or as black as the shadows in summertime. The spring sun is lower in the sky making long shadows, and near sunrise and sunset shadows are at their longest. During the daytime, a shadow cast by an opaque object illuminated by sunlight has a bluish tinge. This is because of ‘Rayleigh scattering’ which also makes the sky to appear blue. The opaque object is able to block the light of the sun, but not the ambient light of the sky which is blue, as the atmosphere molecules scatter blue light more effectively. And so, the shadow appears bluish. Apparently. Although the springtime shadows below definitely look greyish-black.
