title: How to add custom colors to Bulma?
body: <p>I have found this code:</p>
  <pre><code>$custom-colors: null !default
  
  $colors: mergeColorMaps((&quot;white&quot;: ($white, $black), &quot;black&quot;: ($black, $white), &quot;light&quot;: ($light, $light-invert), &quot;dark&quot;: ($dark, $dark-invert), &quot;primary&quot;: ($primary, $primary-invert, $primary-light, $primary-dark), &quot;link&quot;: ($link, $link-invert, $link-light, $link-dark), &quot;info&quot;: ($info, $info-invert, $info-light, $info-dark), &quot;success&quot;: ($success, $success-invert, $success-light, $success-dark), &quot;warning&quot;: ($warning, $warning-invert, $warning-light, $warning-dark), &quot;danger&quot;: ($danger, $danger-invert, $danger-light, $danger-dark)), $custom-colors) !default
  </code></pre>
  <p>How to extend the list of colors and classes associated with each color?
  It's clear I need to define a variable <code>$custom-colors</code> before including Bulma, but it's not clear what format of $custom-colors should be? I didn't find an example or good description of that. Any help?</p>
