The question is pretty simple. Just what the title says.

I was trying to make a very rainy world with extreme variations of precipitation in Fractal Terrains 3, but there did not appear to be a way to specify colors for levels of rain fall above 98 inches a year. Since there were parts of the world with as little as 40 a year, but most above 150 and peaks over 400, the resulting precipitation map looked like a canvas of white with some black veins running through it. All of the parts between 98 and 400 inches (the vast majority of the world) were the same color.

Is it possible to change this in Fractal Terrains 3, or is this unfortunately hard-coded?
