# 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). The x-axis (the line y=0) is positioned at the vertical mid-point of the main read (the main characters on the number plate). The y-axis (the line x=0) is positioned at the center of the number plate, unless Media Server cannot locate the edges of the number plate in which case the line is positioned at the horizontal mid-point of the main read. Each unit on the y-axis is the same as the read height (the height of the main characters on the number plate). Each unit on the x-axis is equivalent to four times the read height.
