Utilize a wine-blush palette with a focus on accessibility. Ensure a 4.5:1 contrast ratio for readability, using primary colors for background and headers, and secondary colors for metrics and highlights.

Utilize a 12-column grid for a 4:3 ratio, placing KPIs at the top for visibility and charts in the middle for analysis. Maintain 16-24px padding and 16-20px gaps between cards for a clean layout.

Set dashboard title at 24-28px bold, section headers at 18-20px semibold, and card titles at 14-16px medium. Use a consistent font like Inter or Segoe UI across the dashboard for clarity.

Select chart types according to data semantics; use gauge for targets, multi-line for trends, and heatmap for allocation insights. Limit colors to 5-7 per chart and add tooltips for context.

Create a strong visual hierarchy by using the largest elements for key metrics and maintaining whitespace to separate sections. Highlight anomalies in key metrics with conditional formatting.

Implement hover states for interactive elements and loading skeletons during data refresh. Provide visual feedback on filter selections to enhance user experience.
