You have an object that’s filled and stroked with just the right colors. Is there a fast way to pick up these attributes and drop them onto other objects?
The Eyedropper tool (I) should do the trick. To pick up the stroke and fill color, click with the Eyedropper on the object that has the right colors applied. Then hold down the Option key (Alt on PC) and the icon changes to a filled Eyedropper ready to drop its picked-up attributes onto any objects you click on, without even selecting them. If you need to change the attributes that the Eyedropper picks up and applies, simply double-click on the tool and change its preferences.
