So i have made triangle path in Illustrator and I want to fill it with the average color of that area. It’s possible in Photoshop with Filter>Blur>Average. Is there an option like that in Ai?
I don’t think theres something like that on illustrator but you can always make a small mosaic and use one of the colours you get:
Go to: Object>create an object mosaic and choose a small number (2 or 3)
If the option is unavailable go to Object>rasterize and when the object is rasterized you’ll be able to make a mosaic.
