Cold, nitpicky, boring. The Reality: Disciplined, detail-oriented, and quality-focused.
Be nice. Do not shout or pressure them. Give them time to process information. If you want a Green to change, you must explain why it is safe to do so. Show them that you care about them as a person.

Flaky, loud, superficial. The Reality: Creative, enthusiastic, and persuasive.
