[USER=450]@Jeremy P[/USER] Ok, I've got even more for you here now after testing with your values and adjusting a bit..
Taking the values you have above, change paletteNeutral3 to xf-intensify(@xf-paletteColor3, 40%)

So, you get a nice low-saturation coral there.. However, when it renders on the front-end:

If you change it to just 20% on the intensify instead of 40%, you get this:

So for whatever reason it's changing the color values improperly with the xf-intensify JUST in the context of that SVG.
