Colors are certainly a significant part of user experience, so although I agree that these issues exist, I disagree with the solutions.

Comments shouldn't be pink/red because they are not necessarily a bad thing. Just make them bold and opaque.

Changing to blue and yellow for diffs is equally as wrong as red/green but more confusing. Blue signifies safe information and yellow signifies warning. It would be better to use the same color for deletions and additions but make deletions darker to show they are stale/rotted and additions brighter to show freshness.
