Hi, wich version of tinyMCE is used with nuxeo ? is it possible to upgrade this version and how can we do that ? thank

Hi,

This cannot be done via Studio unless the plugin is already in tinyMCE, and that does not seem the case for textcolor (current version is quite old): there is an extension point to handle available plugins on this editor, see http://explorer.nuxeo.org/nuxeo/site/distribution/Nuxeo%20Platform-5.8/viewComponent/org.nuxeo.ecm.platform.ui.web.htmleditor.service.HtmlEditorPluginServiceImpl
