AEM Cloud Version : 2021.3.5026.20210309T210727Z-210225 (March 09, 2021)
This post explains adding a plugin to RTE (Rich Text Editor - /libs/cq/gui/components/authoring/dialog/richtext) for adding custom CSS and color to text...
Package install contains a Text component with design dialog with plugin configuration - /apps/eaem-cs-rte-plugin-color-picker/components/text/cq:design_dialog/content/items/tabs/items/plugins/items/eaem-aem-fonts
Demo | Package Install | Github
Plugin Picker
Applying Color
Design Dialog Configuration
Enable Plugin Component Policy
Plugin Config saved in Component Policy
Solution
1) Create the Picker configuration dialog /apps/eaem-cs-rte-plugin-color-picker/clientlibs/fonts-plugin/font-selector and add categories=eaem.rte.font.plugin in /apps/eaem-cs-rte-plugin-color-picker/clientlibs/fonts-plugin/font-selector/jcr:content/head/clientlibs

2) Add any custom styles for the author user to (pick and apply on text using the plugin) in clientlib base eg. /apps/eaem-cs-rte-plugin-color-picker/clientlibs/clientlib-base/rte-fonts.css
.eaem--background-gray{
background-color: #f1f1f1;
}
.eaem--background-white{
background-color: #ffffff;
}
.eaem--background-black{
background-color: #000000;
}
@media (min-width: 992px){
.eaem--content-desktop-hide {
display: none !important;
}
}
@media (min-width:768px) and (max-width:991.95px){
.eaem--content-tablet-hide {
display: none !important;
}
}
@media (max-width: 767.95px){
.eaem--content-mobile-hide {
display: none !important;
}
}
3) Add the plugin execution logic in /apps/eaem-cs-rte-plugin-color-picker/clientlibs/fonts-plugin/clientlib/rte-fonts-plugin.js with categories=[cq.authoring.dialog.all, eaem.rte.font.plugin]
