# Color interpolation
A simple example of color interpolation. I personally prefer HSL, but RGB is commented out if you'd like to us it instead. 

snippet.js

n = 66
var color = d3.scale.linear()
    .domain([0, n])
    .interpolate(d3.interpolateRgb)
    //.interpolate(d3.interpolateHsl)
    .range(['#D40067', '#278ECA'])
    
// Example Code    
height = 224    
data = d3.range(n);
var svg = tributary.g;
    
svg.selectAll("rect")
	.data(data)
    .enter()
    .append("rect")
  	.attr({
      x: 0,
	  y: function(d,i){
      	return i*((height/n)+1)
      },
      width: 390,
      height: height/n,
      fill: function(d,i){
        return color(i)
      },
      opacity: 1,  	    
    })
