 ## `color-gradient`
 
 `color-gradient` outputs a fixed number of colors along a gradient between two existing color variables. A `format` attribute is also required. *Note: The `to` variable must be set in style settings for the gradient to be generated. Also, gradients will only be generated using colors defined under the current style settings `id`.*
