Utilize a teal-coral palette effectively by assigning teal for positive metrics and coral for alerts. Ensure that the contrast ratio meets the 4.5:1 standard for readability.

Implement a 12-column grid for a 4:3 aspect ratio. Place KPIs at the top for visibility, charts in the middle for analysis, and tables or feeds in the lower sections. Maintain 16-24px padding and 16-20px gaps between cards.

Set the dashboard title at 24-28px bold, section headers at 18-20px semibold, and body text at 12-14px regular. Use a clean font like Inter for consistency across the dashboard.

Select chart types that match data semantics: use gauges for targets, maps for geographic data, and tables for detailed metrics. Limit colors per chart to 5-7 to maintain clarity.

Create a clear visual hierarchy with the most important metrics being the largest and boldest. Use whitespace effectively to separate sections and highlight anomalies with conditional formatting.

Incorporate hover states for interactive elements and loading indicators during data refresh. Consider drill-through navigation for deeper dives into metrics.
