### Question

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.

### Accepted Answer

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

- Select two circles you want to create the intersection for.
- Use
`Object â†’ Intersection`

(`Ctrl + *`

) to create the intersection. - Copy the intersection to the clipboard (
`Ctrl + C`

). - Undo the intersection operation (
`Ctrl + Z`

), which deletes the intersection object and restores the original circles. - Paste the intersection object
*in place*(`Ctrl + Alt + V`

,**not**`Ctrl + V`

). - Colour the intersection.
- Repeat steps 1â€“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.

Indeed this is possible in gimp pretty easily.

- Create three circles with colors #ff0000, #00ff00 and #0000ff each to own layer with transparent background
- Add black background layer
- Position those circles as in your image
- Use Additive Blending mode for all of them
- Just remove black background if necessary
