       The linear and adjusted color ramps both worked, but they behaved differently when compared to the ColorBrewer ramp. The linear ramp showed even steps in the RGB values, but the darker colors were still hard to tell apart. This made the lower end of the ramp feel a little flat. The adjusted ramp fixed this by using bigger jumps in the darker colors and smaller jumps in the lighter colors. This made the whole ramp easier to read, especially in the first few classes.      When I compared both ramps to the ColorBrewer version, it was clear that ColorBrewer still looked smoother and more balanced. ColorBrewer ramps seem to be designed so that each step is easy to see, and the colors change at a steady pace. My adjusted ramp came closer to that look, but the ColorBrewer ramp still had the most even and natural progression overall.      For this choropleth map of population change in Colorado, I used a diverging color scheme and a Natur...
