Summary
[edit]DescriptionFour color theorem (17248418448).jpg |
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 <a href="https://www.flickr.com/photos/carloszgz/sets">my gallery</a>, 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. I’d very much appreciate if you give photo credits to “Carlos ZGZ” when you use this picture. This would help me find it and add it to my photoset <a href="https://www.flickr.com/photos/carloszgz/sets/72157651104515768">“Used elsewhere”</a>. __ Como todas las imágenes de <a href="https://www.flickr.com/photos/carloszgz/sets">mi galería</a>, esta es una imagen LIBRE.
