Colour by state

The objects take a colour for each state of the entity, and their own colours in the other states.

- entity: binary_sensor.front_door
  type3d: color
  object_id: Front_door
  colorcondition:
    - state: 'on'
      color: '#ff0000'
    - state: 'off'
      color: green

A colour is #rrggbb, a name (red) or r, g, b (255, 0, 0). With an entity_template the state can be made from a number: hot above 25 °C, for example.

The colour of a light

With color.light: yes (since 2.13.4) the objects take the colour of a light entity while it is on, and glow with its brightness: a LED strip, a lamp shade, a lit sign. The entity is the light itself.

- entity: light.kitchen_led_strip
  type3d: color
  object_id: Led_strip
  color:
    light: yes
    glow: 1.5

Option	Default
light	no	yes: while the entity is on, the colour it reports (rgb_color, or its colour temperature; white when it reports none).
glow	1	How much the objects glow, times the brightness of the light. 0: coloured, without glow.

Off, the objects have their own colours again. A colorcondition whose state is the state of the entity comes first: unavailable in grey, for example. The glow doesn’t light the room: for that, give the lamp a light entity too.

The card can also colour the doors and the rooms by itself: open doors in amber, rooms by temperature, presence or any sensor (see the state_colors and rooms options).
