# ColorRegion

Specifies the region to output to the `ColorRegionWithSource` output track, so that you can configure an analysis task to identify the color of the vehicle.

Set this parameter to one of the following values:

- `front` - use this value when the source frames show the front of the vehicle.
- `back` - use this value when the source frames show the rear of the vehicle.
- a custom region (left, top, width, height). When you set a custom region the co-ordinate `-0.5,-0.5` represents the top left corner of the number plate, `0,0` represents the center, and `0.5,0.5` represents the bottom right corner of the number plate. This means that a width of `1` represents the width of the number plate, and a height of `1` represents the height of the number plate.
