It makes me think about all the people that have committed suicide, they are floating around us and their dead hasn't been in vain. They were regular people as you and I, and if we live in a world where we have to act like we don't care, when we actually really care, then we need to change it. I believe the song is talking from the perspective of someone who has experience true freedom and saw all the beautiful colors, this beautiful pallet is unique, cool and it only belongs to you. Perhaps realized that shouldn't really care about all the reasons that pushed him/her to commit suicide, they were irrelevant and only make sense in the box we have crafted, called reality. To me is saying that it is enough if you know about this change, no need to tell at the end what counts is that we are aware of our own ignorance.
