Like the moon during an eclipse?

Yes...except that we want sufficient light to still come through and illuminate the rest of the sky to give us that nice Raleigh scattering blue colour over the portion of sky that is not blotted out by the disk.

A total solar eclipse would cut off substantially all sunlight; we want enough sunlight around the periphery of the disk to give us a blue sky.
