Utilize the cobalt-rose palette effectively by using cobalt (#0047AB) for headers and navigation, rose (#FF6B81) for key metrics, and an accent color (#1976D2) for secondary elements. Ensure a contrast ratio of at least 4.5:1 for accessibility.

Implement a 3x3 grid structure to maintain a 4:3 aspect ratio. Place KPI cards in the top row for immediate visibility, followed by charts in the middle for analysis, and filters in the sidebar. Maintain a 16px padding and 20px gaps between cards for clarity.

Use a clear typography hierarchy: Dashboard title at 28px bold, section headers at 20px semibold, card titles at 16px medium, body text at 14px regular, and captions/labels at 12px. Maintain a single font family (e.g., Inter) for consistency.

Select chart types that match the data narrative: use Multi-Line Charts for trends, Horizontal Bar Charts for comparisons, and Gauges for targets. Limit colors per chart to 5-7 and add tooltips for context. Ensure consistent axis formatting.

Create clear visual hierarchy by making the most important metrics larger and bolder. Use whitespace to separate sections and add subtle shadows to cards for depth. Highlight anomalies in red for negative and green for positive changes.

Incorporate hover states for interactive elements with subtle opacity changes. Use loading skeletons during data refresh and provide visual feedback on filter selections. Consider implementing drill-through navigation for deeper insights.
