I managed to get colors by eventtype on my search results following this tutorial : http://blogs.splunk.com/2014/10/05/look-at-all-the-pretty-colors/
However those colors are not displayed when I display the same search inside my dashboard, and I don't knpw what I am missing...
I finally found how to solve this
All I had to do was to efit the event_renderers.conf in the user/search/local folder and grant access to search to those users.
