Resolution steps

The RGB color elements were converted to HEX formatting by TinyMCE, the WYSIWYG editor used for the content management of the help center. As a workaround, edit your articles to use RGBA instead, for example rgba(255, 99, 71, 0.5). RGBA elements do not automatically get converted into HEX.
