   ## Attributes
 
-  *   `colorFamilies` (*type:* `list(String.t)`, *default:* `nil`) - The standard color families. Strongly recommended to use the following standard color groups: "Red", "Pink", "Orange", "Yellow", "Purple", "Green", "Cyan", "Blue", "Brown", "White", "Gray", "Black" and "Mixed". Normally it is expected to have only 1 color family. May consider using single "Mixed" instead of multiple values. A maximum of 5 values are allowed. Each value must be a UTF-8 encoded string with a length limit of 128 characters. Otherwise, an INVALID_ARGUMENT error is returned. Google Merchant Center property [color](https://support.google.com/merchants/answer/6324487). Schema.org property [Product.color](https://schema.org/color).

The colorFamilies field as a system attribute is not a required field but strongly recommended to be specified. Google Search models treat this field as more important than a custom product attribute when specified.
   *   `colors` (*type:* `list(String.t)`, *default:* `nil`) - The color display names, which may be different from standard color family names, such as the color aliases used in the website frontend. Normally it is expected to have only 1 color. May consider using single "Mixed" instead of multiple values. A maximum of 75 colors are allowed. Each value must be a UTF-8 encoded string with a length limit of 128 characters. Otherwise, an INVALID_ARGUMENT error is returned.
