                    value to an rgb, rgba, hex, hsl, hsv, or named

                name
                    When used in a template, named items are

                    matching this `name` alongside your
                    modifications (including `visible: false` or

                    outside of a template.
                templateitemname
                    Used to refer to a named item in this array in
                    the template. Named items from the template
                    will be created even without a matching item in
                    the input figure, but you can modify one by
                    making an item with `templateitemname` matching
                    its `name`, alongside your modifications
                    (including `visible: false` or `enabled: false`
                    to hide it). If there is no template or no
                    matching item, this item will be hidden unless
