Color and Choropleth

 This week, we experimented with color ramps and worked to develop a deeper understanding of how color is used to develop more meaningful and beautiful maps.  Below is a map of population change in the state of Colorado from 2010 to 2014.  I used a 4 part color ramp with two classes showing population increase and two classes showing population decrease.  I used a divergent color ramp from Color Brewer and manually created the colors on my ramp using the RGB values listed on Color Brewer.
