Recolor a pattern.
In Illustrator, open the Libraries panel (Window > Libraries). Select the UNWRP Patterns library, available at the top of this page, and double-click a pattern swatch to open it in a new document. Select the pattern with the Selection tool (Ashley chose UNWRP Pattern 4).
Choose Edit > Edit Colors > Recolor Artwork and drag the handles to experiment with color combinations. Use the large handle to set the overall color theme and the small handles to change individual colors. Then click on the artboard to set the changes when you’re done.
Pro tip: Use Generative Recolor (Edit > Edit Colors > Generative Recolor) to change colors using text prompts or presets.
