              autocolorscale
                  Determines whether the colorscale is a default
                  palette (`autocolorscale: true`) or the palette
                  determined by `marker.colorscale`. Has an
                  effect only if colorsis set to a numerical
                  array. In case `colorscale` is unspecified or
                  `autocolorscale` is true, the default  palette
                  will be chosen according to whether numbers in
                  the `color` array are all positive, all
                  negative or mixed.
              cauto
                  Determines whether or not the color domain is
                  computed with respect to the input data (here
                  colors) or the bounds set in `marker.cmin` and
                  `marker.cmax`  Has an effect only if colorsis
                  set to a numerical array. Defaults to `false`
                  when `marker.cmin` and `marker.cmax` are set by
                  the user.
              cmax
                  Sets the upper bound of the color domain. Has
                  an effect only if colorsis set to a numerical
                  array. Value should have the same units as
                  colors and if set, `marker.cmin` must be set as
                  well.
              cmid
                  Sets the mid-point of the color domain by
                  scaling `marker.cmin` and/or `marker.cmax` to
                  be equidistant to this point. Has an effect
                  only if colorsis set to a numerical array.
                  Value should have the same units as colors. Has
                  no effect when `marker.cauto` is `false`.
              cmin
                  Sets the lower bound of the color domain. Has
                  an effect only if colorsis set to a numerical
                  array. Value should have the same units as
                  colors and if set, `marker.cmax` must be set as
                  well.
              coloraxis
                  Sets a reference to a shared color axis.
                  References to these shared color axes are
                  "coloraxis", "coloraxis2", "coloraxis3", etc.
                  Settings for these shared color axes are set in
                  the layout, under `layout.coloraxis`,
                  `layout.coloraxis2`, etc. Note that multiple
                  color scales can be linked to the same color
                  axis.
              colorbar
                  :class:`plotly.graph_objects.treemap.marker.Col
                  orBar` instance or dict with compatible
                  properties
              colors
                  Sets the color of each sector of this trace. If
                  not specified, the default trace color set is
                  used to pick the sector colors.
              colorscale
                  Sets the colorscale. Has an effect only if
                  colorsis set to a numerical array. The
                  colorscale must be an array containing arrays
                  mapping a normalized value to an rgb, rgba,
                  hex, hsl, hsv, or named color string. At
                  minimum, a mapping for the lowest (0) and
                  highest (1) values are required. For example,
                  `[[0, 'rgb(0,0,255)'], [1, 'rgb(255,0,0)']]`.
                  To control the bounds of the colorscale in
                  color space, use`marker.cmin` and
                  `marker.cmax`. Alternatively, `colorscale` may
                  be a palette name string of the following list:
                  Greys,YlGnBu,Greens,YlOrRd,Bluered,RdBu,Reds,Bl
                  ues,Picnic,Rainbow,Portland,Jet,Hot,Blackbody,E
                  arth,Electric,Viridis,Cividis.
              colorssrc
                  Sets the source reference on Chart Studio Cloud
                  for  colors .
              depthfade
                  Determines if the sector colors are faded
                  towards the background from the leaves up to
                  the headers. This option is unavailable when a
                  `colorscale` is present, defaults to false when
                  `marker.colors` is set, but otherwise defaults
                  to true. When set to "reversed", the fading
                  direction is inverted, that is the top elements
                  within hierarchy are drawn with fully saturated
                  colors while the leaves are faded towards the
                  background color.

                  ` instance or dict with compatible properties
              reversescale
                  Reverses the color mapping if true. Has an
                  effect only if colorsis set to a numerical
                  array. If true, `marker.cmin` will correspond
                  to the last color in the array and
                  `marker.cmax` will correspond to the first
                  color.
              showscale
                  Determines whether or not a colorbar is
                  displayed for this trace. Has an effect only if
                  colorsis set to a numerical array.
