         Given a depth matrix between 0-1, return a color from a given colormap.
         The colormap is a list of tuples containing the depth value, and the
         color for this level :
-            (depth_value, [RedVal, GreenVal, BlueVal])
+        (depth_value, [RedVal, GreenVal, BlueVal])
 
         The colormap should at least contain a color for the depths 0 and 1.
         See COLORS for an example colormap.
