Hello World

Custom Map Color Palette Generator

Problem: You’d like to design a custom map style that matches your brand, your school or team colors, holiday colors, or you just want to have fun. There are tools to do this, but maps are complicated, with dozens of layers of place types, road types, water types, land types, big labels, big labels...all with different shades and line weights to create a pleasing design. Try to design all of this yourself, and you’ll be pulling your hair out.

Solution: Hire a cartographer, OR give MapJam’s autoPalette Javascript function a try. Just feed it one or two colors and, it will shade dozens of map elements on-the-fly with a top secret proprietary formula (actually, you can just look at our code!)
