to bend. If the light source emanates from numerous directions and points, you will see several shadows, some of them overlapping. Depending on the color of the light, you will also see shadows of different lights and shades.
Colored shadows, for the most part, are generated when the multicolored light sources produce white light. If there is no white, the complementary hue for the lights that are being blocked will be reflected on the shadow. For example, if the light is blue, then the shadow that will appear is red, while for green, it can be yellow or purple, depending on the shade.
With these explanations, it should be obvious why the time of day plays a vital role in forming shadows, the sun being the primary source of light on the objects around you. However, it would be appropriate to dismiss a myth here right now, which is that shadows get longer as the day fades. The opposite is in fact the case.
Knowledge is power, it is said, and this is certainly true in this case. The next time that you are forming shadow puppets on the wall, you will have a better idea of how these tricks of light are formed.
