Loop the Loop

A gentle Challenge.

Can you replicate this:



The inner circle starts at 1cm and each successive radius is 1cm larger.

Choose your own colours.

I would prefer to also here how you constructed your design.

siran, 100%. I never even thought of the opacity mask.

I just used a semi-circle as a cutter to get the same as your overlay approach.




If you repeat for the other grouped circles, you can extend the shapes as a frieze or pattern.

I am not sure if the same method could achieve Gary's four-leafed clover.

Gary, thank you for this too! I 'see' the two overlapping circles, side-by-side, and the yin-yan effect but no levels of graduation.

Sorry about that,
Acorn

Late again, sorry.
