**Color By** options

Change the color scheme of annotation:
- Job status: ``annotation``, ``validation`` or ``completed`` task
- ``Instance`` — every bounding box has random color

_Overview_:
- ``Group`` — every group of boxes has its own random color, ungrouped boxes are white
- ``Assinger`` - the one to whom the job is assigned.
- ``Start Frame`` - the number of the first frame in this job.
- ``End Frame`` - the number of the last frame in this job.
- ``Frames`` - the total number of all frames in the job.
- ``Z-Order`` - z-order enable indicator.

_Annotations statistics_:
- ``Label`` — every label (e.g. vehicle, pedestrian, road marks) has its own random color
This is a table number of created shapes, sorted by labels (e.g. vehicle, person)
and type of annotation (shape, track). As well as the number of manual and interpolated frames.

#### UI switcher

You can change any random color pointing on needed box on a frame or on a
