Light Speed travel and Invisibility?

Could an object traveling at faster than light (I know its impossible but for this question lets assume it isnt) conceivably be invisible to the naked eye? Since the eye requires light to register images would an object traveling faster than light not give off color and hence not be observable?

Imagine a jet fighter. It travels faster than the speed of sound, but that does not make it inaudible. Regardless of the consequences of time travel and infinite energy requirements, an FTL object with mass would encounter normal matter in its path and collide with massive consequences, which would certainly be visible.
