Using 3333ff

3333ff 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

}

.button-primary {
  background: var(--color-3333ff);
  color: #ffffff;
}

$3333ff: #3333ff;

// Tailwind arbitrary value
