The RGB filter can be used to focus on pixels that are the most green, blue or red within the image. Instead of looking for a specific RGB value the RGB filter can even identify green objects in lower or brighter lighted areas. You can select as many colors as needed and track them simultaneously.

If you prefer to manually decide on which colors you would like to eliminate you can use the Threshold module to do so. Using this module you can narrow your focus towards a very specific color.
