Sometimes picking out the ideal color scheme for your map can be quite the challenge, especially when you have a large number of classes you need to show on the same map. Well, in these instances, you might want to check out Penn State University’s (PSU) Color Brewer 2.0 which is a website full of color advice! I found out about this website back in my graduate school days and have been using it ever since. Some of my favorite features of the site include:
- The ability to split your color scheme across a minimum of 3 categories and up to 12.
- There are color schemes for a variety of data types and then a variety of hues within these data types.
- There is an option for colorblind-safe schemes.
- And as an added bonus, you can export the color HEX/RGB/CMYK to a variety of formats in order to load them in your mapping application.
Nice work Cynthia Brewer and Mark Harrower of PSU – thanks for sharing this great site!
Until my next edition of the Free For All, happy hunting for free geospatial goodies!
