When it comes to outdoor shadows I know that they ‘may’ have a bluish tint because of the fact that the sun creates the shadow so no light from the sun can get into the shadow. However, the indirect lighting from the blue sky would be able to color the shadow, which would give it a blue tint. Now this makes sense to me, because at least their some kind of logic to it.
However, I remember someone said that the reason shadows have a blue tint outside is because the sun’s light is yellowish orange and that it’s complimentary color is blue hence why shadows outside are blue tinted. Basically he was saying that whatever color the light is, the shadow would be tinted that light’s complementary color. The only reason I’m wondering about it is because he said he took a color theory class and that’s what he was taught. To me though, this sounds like nonsense because the color for the shadows needs to come from somewhere. Does anyone know if there’s any truth at all to what that guy was talking about, or were they just misinformed?
