Design a complete color palette system for a wellness brand using monochromatic principles. Write in a {{tone}} tone for {{target_audience}}. The primary use case is {{platform}}, and the goal is {{goal}}. Include: Color Strategy, Primary Palette (3 colors with full values), Secondary Palette (3 colors), Semantic Colors (success, warning, error, info with variants), Extended Tint & Shade Scale (50-900 steps), Dark Mode Adaptation, Color Pairing Rules (at least 10 pairings with WCAG AA ratios), and Application Examples. Maximum 1800 words. Use Markdown headers and bullet points. Bold key terms. Provide HEX, RGB, HSL, CMYK, and Pantone values where requested. Note WCAG AA compliance for each step. If a Pantone match cannot be determined, output DATA_UNAVAILABLE. All recommendations must be specific to the wellness industry and {{target_audience}}. Paste any relevant background information after these instructions before running.
