A method of implanting an intervertebral implant with differentiation of tissue includes: providing electromagnetic radiation into an intervertebral space； visualizing a first color of a first tissue portion located at the intervertebral space, the first color being in response to the provided electromagnetic radiation； visualizing a second color of a second tissue portion located at the intervertebral space, the second color being differentiated from the first color in response to the provided electromagnetic radiation, wherein the first tissue portion and second tissue portion are both substantially similar under normal ambient light； visualizing damage to an intervertebral disc between adjacent vertebras from the first color and the second color； and inserting an intervertebral implant into the intervertebral space.
