One problem is the color.  From the documentation (section 3.5.11.4):
"The bozo pattern has a default color_map built in that results in a 
green, blue, red and white pattern with sharp transitions."

If you don't want such colorful fog, see section 3.6.2.3.2,  "Density 
with color_map."

Hope this helps.
