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.
The Rainbow colormap is provided to give a rainbow effect with uniform color and lightness difference, the hue differences can lead to false features in data, so care should be taken when using it.
This colormap isn't quite centered when converted to grayscale.
This colormap is not really suitable 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.
