Today we are excited to release Global Colors for Divi, a new dynamic color system that allows you to create and control colors across your entire website. Now you can build your own dynamic color palette of global colors. When you change a global color, all elements using that color are updated. That means you can control your entire website’s color scheme from a single location while using the builder; adding and managing colors as you see fit.
