Want to know how to create circle effect? Then read on.
Create a new document. Choose the Eclipse tool and draw an eclipse. Draw two more ellipses and give them different colours.
Choose all the circles and place one in the front of the other and group them (see the image below).
Then copy the group of circle and paste it. Make copies as many as you like.
After that, ungroup the circles.
To select objects with the same colour navigate to Select > Same > Fill Colour.
This is the effect that you will get.
Want to make the design even better? Try to add ink splatter symbols.
