You can reference colors in the palette by number in most commands that understand color names.
You can programmatically access the colors using ColorTools commands.
Cividis is best used to construct as a sequential gradients from dark to light and from bluish to yellowish via gray.
This colormap is good when converted to grayscale.
This colormap is also reasonably good for users with CVD.
The Blend command can be used to create a function to color arbitrary ranges. It can take the name of a palette to generate a colormap.
And is particularly good when used to color surfaces. The colorscheme option of plots can take the names of palettes to generate gradients.
