A workmate in crime from Brisbane office, Gerhard Pretorius, recently posted an interesting tricks to change On-Premise Deployment with Sandbox Colour Scheme that currently only available on CRM Online:

To make an On-Premise CRM system display the “Sandbox Theme”, you will need to do some code…

Just a note – this is only available for CRM 2013 RU2 and up. THIS IS AN UNSUPPORTED CUSTOMISATION!

Edit the main.aspx file on the CRM server, this is usually located at C:\Program Files\Microsoft Dynamics CRM\CRMWeb\main.aspx. In the head section of main.aspx, after the title tag add the following tag (replace OrgName with your CRM Organisation name):

<script>

Restart the CRM Server / do an IIS Reset.

Only the sandbox instance will now show the orange “Sandbox Theme”. This is a great way for users to know which system they are in.
