The procedure for requesting AWR support has changed. Please read all about the new AWR product support process.
How do I change the color settings in Microwave/Analog Office?
On the main menu, select Options > Environment Options > Colors tab.
You can change the color of schematics, system diagrams, equations, etc. Note that color settings (and all environment settings) are persistent. They will remain across multiple sessions of the AWR Design Environment.
Refer to Tip of the Day for more on this.
