Folks, some of you may have figured out how to get the pure CMYK colors (so that our maps will POP out so much Nicholas will have to run and hide!), but here is how to do it:
When you are selecting a color (for any symbol or whatever, it doesn't matter), choose More Colors..., then there is a little black arrow at the top right. Click on that, and change the sliders to CMYK sliders. Then you can maximize each hue and, this is important, SAVE the color by clicking on the arrow again. Now when you go to choose colors, you will have your new saved colors in the top left.
