How to draw 3 overlapping circles with different colors?

Is there a free software to draw following in ubuntu? How to color the overlap zone? I am not able to figure this out in GIMP.

Answer

You can use Inkscape. Basically, you’ll have to break the circles into several parts, one for each possible intersection of circles:

  1. Select two circles you want to create the intersection for.
  2. Use Object → Intersection (Ctrl + *) to create the intersection.
  3. Copy the intersection to the clipboard (Ctrl + C).
  4. Undo the intersection operation (Ctrl + Z), which deletes the intersection object and restores the original circles.
  5. Paste the intersection object in place (Ctrl + Alt + V, not Ctrl + V).
  6. Colour the intersection.
  7. Repeat steps 1–6 for the remaining pairs of circles, and again on the three two-circle intersections (to create the middle intersection).

You might also want to use the difference operator (Ctrl + -) on the outer circles to cut out the shape of the inner parts.
