I gotta agree with whats already been said about using blue tape.
an lets just say that these deer do see the tape, How many deer have you saw while hunting were watching you but just pulled back into the brush, waiting for you to pass on by? Even if deer can supposedly see the color "blue" it doesnt mean its goona spook them,
Im also thinkin that if that deer can see your tape, then it has allready got you pegged for what you are
