    Question Three Overlapping Circles

    You may start from the solution to https://www.talkgraphics.com/showthr...uching-Circles.
    Attachment 122412
    You, however, can create a Red, Green and Blue circle from afresh, each with a diameter of 200px.

    The Challenge is to simply, and accurately, position the circles so that each circle equally intersects (overlaps) the other two circles but there is no overlap with all three circles.

    To achieve the primary colors creating the secondary colors I used magenta, yellow and cyan with Multiply (Stained Glass) transparency.

    Gary, got it in one!
    I thought my misdirection from the first Challenge would throw people off.

    Thank you too for the creation of the primary colours in the overlap; a sign of true knowledge.

    For those who are interested, the design can be expanded readily into what is called the Seed of Life, http://mathworld.wolfram.com/SeedofLife.html:

    I will leave a final Challenge for you to draw the Flower of Life: http://mathworld.wolfram.com/FlowerofLife.html.

    The trick for both is actually to use the technique for the Venn Diagram solution, which I hope you will have a go at as well.
