Color Palette Customization
By default, Curtain automatically pick a color from a pastel color palette for most of its visualization. You can access this through Plot-> Customize Color Palette.

Here you can change the color palette automatically used by Curtain. You can see a set of currently used color in the Current Palette section. If you want to change the color palette, you can select one of the built-in palette under Select a built-in palette dropdown or click Customize Palette to give you the ability to manually changing the colors as well as adding how many colors that you want into the rotation. The following are the available built-in palettes:
