✓Save your palette as HEX codes so it is easy to reuse across tools.
✓Everything runs locally in your browser — your input is never uploaded to a server, so it is safe for private or sensitive data.
✓Test colors in both light and dark UI contexts before shipping.
✓Pair with the palette and gradient generators for full theming.
✓Keep text and background contrast high (aim for WCAG AA 4.5:1) for accessibility.
