Comment (by Lwangaman):

 Using the 'color-picker' icon in an html element using css classes works
 fine:

 {{{
 <h2 class="dashicons-before dashicons-color-picker">A Colorful
 Headline</h2>
 <h2><span class="dashicons dashicons-color-picker"></span> A Colorful
 Headline</h2>
 }}}

 both work fine. It is only when using the string 'color-picker' to
 indicate the icon when creating a Gutenberg PanelBody that the icon is not
 shown:

 {{{#!javascript
 createElement(PanelBody, { title: __('Background color','textdomain'),
 initialOpen: false, icon: 'color-picker' }
 }}}
 Icon not shown. Other icons work fine:
 {{{#!javascript
 createElement(PanelBody, { title: __('Layout options','textdomain'),
 initialOpen: false, icon: 'admin-appearance' }
 }}}
