# ColorRegion

Specifies what to output to the `ColorRegionWithSource` output track, so that you can use color clustering to identify the color of the vehicle.

Micro Focus recommends that you do not set this parameter. By default, Media Server uses a neural network to identify the vehicle within the image or video frame. This approach is likely to provide the best accuracy.

To use the legacy behavior, which selects a fixed region based on the position of the number plate, set this parameter to one of the following:

- `front` - the source frames show the front of the vehicle.
- `back` - 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.
