and if it did, what color would the "shadow" be?

A hologram does not produce a shadow, since the object it shows is done by interference in the plane of the hologram.

Will antimatter produce a shadow when put under light?
Also, would metamaterials produce a shadow? if it bends light around it, then there wouldnt be a shadow, right?
P.S. an admin can change this thread to "shadows" if they want. (i dont care).

I would think antimatter would behave just like matter (only with some mirror image effects). A reversal of elementary particle charges should not have any relation to whether or not the object composed of these particles has a shadow.
As for light bending around an object, that sounds considerably different. Shadows, after all, are just areas where light has been intercepted by an object situated between the surface upon which the shadow is cast and the source of this light. So my thinking is in line with yours that if the light from this source is diverted around an intervening object, then the object hasn't intercepted any light -- and thus casts no shadow.

i'd think it produce the color of the color it is. sort of like putting a colored lense on a flash light
