The default colors used to be (in 2007):

Positive draft = Green

Requires draft = Yellow

Negative draft = Blue

In newer releases the default colors are:

Positive draft = Green

Requires draft = Yellow

Negative draft = Red

This creates a major (IMHO) problem when using "Gradual transition" because areas with zero draft AND areas with adaquite draft (in the negative direction) are BOTH Red!  Is there any way to change the DEFAULT colors so that I don't have to edit the color every single time I use the feature (which I do very often)?
