How to set the color theme of for production and sandbox by default ?

AI generated answer (using internal Slack threads):

In NetSuite, there is no global option to set a default "Color Theme" for all users in both production and sandbox environments. The color theme can be set on a role-by-role basis. This can be done by going to the Role record and setting the color theme under the preference subtab. However, it's important to note that users can override this in their Set Preferences. Here are the steps to set the color theme for a role: 1. Navigate to Setup > Users/Roles > Manage Roles. 2. Edit the role for which you want to set the color theme. 3. Go to the Preferences subtab. 4. Set the color theme. 5. Save the changes. Remember, this change will only affect new sessions; users who are already logged in will not see the change until they log out and log back in. Also, keep in mind that these settings will be overwritten each time the sandbox account is refreshed. So, you will need to repeat this process after every sandbox refresh. Unfortunately, there is no way to lock the color theme or to set it globally for all users. This is considered an enhancement in NetSuite. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
