## Day 9

2020-11-09 - Monochrome - *A monochromic image is composed of one color (or values of one color). So for example black and white maps are valid here. [See some inspiration from the great monochrome mapping competition](https://somethingaboutmaps.wordpress.com/monocarto-2019-winners/) (although those masterpieces took a bit more than a day to make, probably).*
