Dreamweaver uses color to help you write your HTML and other forms of code. And you can use this window to update the color schemes for many different forms of code.
Highlight the code you'd like to edit and click on the "Edit Coloring Scheme" to change the colors of various parts of the specified code.
You can also change the background color of your code view on this page.
Once you've updated the code colors, click "OK" to save your preferences.
