Customize Preview Active Toolhead Coloring

[doberbrown]

I'm somewhat color blind/deficient and I am not able to distinguish between the (what I'm told) are green and blue colors that are used in the preview mode when the coloring is changed to Active Toolhead. I love everything else about Simplify3D and really want it to work for me, but until I'm able to customize those colors, I don't know if things are going to work out for me.

TLDR: PLEASE add the ability to change the colors for active toolhead in preview mode!
