Color

Use shorthand color utility classes to quickly apply or remove colors.

Icon color#

Change icon colors with contextual classes.

Brand#

Brand icon colors reinforce Lumen's brand. Use primary and secondary as accents, and dark, grey, and light as neutrals.

<!-- For light backgrounds -->
<i class="chi-icon icon-atom -md -icon--dark"></i>
<i class="chi-icon icon-atom -md -icon--primary"></i>
<i class="chi-icon icon-atom -md -icon--grey"></i>
<!-- For dark backgrounds -->
<i class="chi-icon icon-atom -md -icon--secondary"></i>
<i class="chi-icon icon-atom -md -icon--light"></i>

Semantic#

Use semantic text colors to communicate meaning to users. Examples include displaying alerts, form field validation, user status, application state and more. Use green (success) for positive, blue (info) for informative, red (danger) for negative, yellow (warning) for needs attention, and grey (muted) for neutral. Semantic colors should never be used for decorative purposes.

<i class="chi-icon icon-atom -md -icon--warning"></i>
