When you have an area of mostly a primary colour next to something else, 
you often need to reduce the threshold quite a bit.
In this case, with green next to a dark area, you need to reduce the 
threshold at least by a factor of 3. So, it should be less than 0.1. You 
may need to go down to about 0.01 to get a good result.
