Using Cc0000

Cc0000 works best when it is chosen with contrast, surrounding colors, and interface state in mind. Use the HEX value for static CSS, RGB when you need channel-level control, and HSL when adjusting lightness or saturation for hover states. The CMYK value is an approximate screen-to-print conversion, so print workflows should still rely on calibrated design software or a printer profile.

CSS, SCSS, and Tailwind examples

:root {
  --color-cc0000: #cc0000;
}

.button-primary {
  background: var(--color-cc0000);
  color: #ffffff;
}

$cc0000: #cc0000;

// Tailwind arbitrary value
class="bg-[#cc0000] text-white"
