Extended Chart Palette

For charts requiring more than 2 colors, use this sequence:

const chartColors = [
  '#ED4B82',  // Primary Pink
  '#4361EE',  // Primary Blue
  '#F472B6',  // Medium Pink
  '#6366F1',  // Indigo
  '#1E3A5F',  // Dark Blue
  '#F9A8D4',  // Light Pink accent
  '#818CF8',  // Light Indigo
  '#BE185D',  // Deep Pink
];

Logo Assets

Logos are available in assets/:

• logo-openhexa.png - OpenHexa logo (pink hexagon)
• bluesquare-logo.svg - Bluesquare logo (blue with white text)

Logo Usage in HTML

<!-- OpenHexa logo in header -->
<img src="assets/logo-openhexa.png" alt="OpenHexa" style="height: 40px;">

<!-- Bluesquare logo in footer -->
<img src="assets/bluesquare-logo.svg" alt="Bluesquare" style="height: 24px;">

Logo as Base64 (for standalone HTML)

When creating standalone HTML files, embed logos as base64 to avoid external dependencies. Read the logo files and convert them inline.
