How does Death find relief from the strain in his job?

Death explains that it deliberately tries to notice colors -- as opposed to bodies and people -- in its line of work as a way of distracting itself from the survivors, whom Death considers to be more tragic than the actual dead.

Death uses the colors of the sky to keep his mind off of what he does to people every second of each day. This portrays that Death actually doesn't like his job, and isn't all about taking people's souls.
