All things have degrees, as it were. Light and darkness has varying levels of both. Most people have never seen total darkness.
While there is no darkness is God, we are told that there are things that He calls abominations, and other things that He does not term that way. Lying is "evil", except when it is done to save the lives of two spies in the Bible.
God list things that He loves, seemingly more than other "good" things.
Very little in life is black or white.
