QLD Copyright Concern Over Guitar Named after DC Comic Hero?

Hi there, I have been making a guitar that is white and would like to know if I sell it a) in Australia or b) Overseas, do I need to change the name from "White Lantern" to something else generic? FYI, the White Lantern is from DC Comic Books. Think, the Green Lantern, but white.

This guitar is in a white colour that has a wavelength of 591nm and AFAIK. This is not copyearight (eg: Cadburys Chocolates and the colour purple) and it's already too late to change the colour. It bears no resemblance to DC's White Lantern, nor does it have any markings to suggest DC's White Lantern is in anyway involved with or has a commercial relationship with this guitar. It's just what I have called it. I hope this is enough information.
