Syntax Highlighter Is Wrong

Only we humans get to judge which changes are good and which are bad, but during code review, the diff viewer is constantly subtly trying to influence our judgment. I have showed how these judgments are made by our existing code highlighting themes: comments are hidden as unimportant, and deletions are displayed as errors. Further, I demonstrate that the judgments made by our existing color themes are the polar opposite of those that we wish to convey: comments are important, and deletion is neither dangerous nor improper.
