Hi Mohamed

That looks like the colours that are set in System Admin for the sidebar - speak to someone in your company that has Jira System Admin rights

[Andy Heinzer]

If you have Jira system admin rights, then please see Configuring the look and feel of your Jira applications.  It explains how you can change the settings in Jira to customize these colors.   But as Warren explained, if you are not a system administrator, you won't be able to change this yourself.
