The wavelength has negligible effect on shadow geometry (yes, there is chromatic aberration, refraction, interference but those are very minor in normal lighting, you need special prisms, tiny slits and perhaps lasers to really observe them). What do you even mean?
Also, sunlight (6000K) and daylight (6500K) is pretty much the same color because direct sunlight is >90 % of daylight (the rest is the blue sky and white clouds).
