This example helps to show how the isolated areas of a Venn diagram can be filled / coloured. It was created as part of this answer on TeX StackExchange. Other options for creating Venn diagrams with multiple areas shaded can be found in the Overleaf gallery via the Venn Diagrams tag.

Venn Diagrams in LaTeX

With TikZ 3.0, there’s a new kind of transparency: you can use blend modes. This short Venn diagram example shows how the screen blend mode can be used to create a clear visual effect with just a few lines of code. Overall, there are 16 blend modes to choose from: normal, multiply, screen, overlay, darken, lighten, color dodge, color burn, hard light, soft light, difference, exclusion, hue, saturation, color, luminosity. The code for this example was written by Paul Gaborit, published on TeX.SE and then on TeXample.net. This abstract is adapted from that on TeXample.

A Venn diagram with triangles

La bandera actual de Burundi fue adoptada el 28 de junio de 1967, luego de independizarse de Bélgica el día 1 de julio de 1962. Su diseño consiste en una Cruz de San Andrés en "X" que divide un fondo de cuatro triángulos en verde y rojo, colores que dominan en las tres estrellas centrales inscritas en un círculo blanco. La relación alto/ancho de la bandera fue de 2 a 3 hasta el día 27 de septiembre de 1982 cuando cambió a 3 a 5. La hoja de construcción de la bandera y sus colores se han tomado de la página http://vexilla-mundi.com/burundi_flag.html.
