Four color theorem

The idea of this picture came to me while playing around with the "four color theorem". This theorem states that, given any separation of a plane into contiguous regions, producing a figure called a map, no more than four colors are required to color the regions of the map so that no two adjacent regions have the same color. Well, in this case only two colours are needed: black and white. And I love the result! __ As all the pictures in my gallery, this is a FREE picture. You can download it and do whatever you want with it: share it, adapt it and/or combine it with other material and distribute the resulting works. Iâ€™d very much appreciate if you give photo credits to â€œCarlos ZGZâ€ when you use this picture. This would help me find it and add it to my photoset â€œUsed elsewhereâ€. __ Como todas las imÃ¡genes de mi galerÃa, esta es una imagen LIBRE. Puedes descargarla y hacer lo que quieras con ella: compartirla tal cual, modificarla y/o combinarla con otro material y distribuir el resultado. Por favor, si utilizas esta imagen, dale el crÃ©dito a â€œCarlos ZGZâ€. De esta manera podrÃ© encontrarla fÃ¡cilmente y aÃ±adirla a mi Ã¡lbum â€œUsed elsewhereâ€.
