There's really no easy way to do this.  You'll have to convert the image to
an array of pixels, then search through them to find a block of the color
you're interested in.  Remember that camera sensors are real-world devices,
so the actual pixel values vary slightly from frame to frame.  You'll have
to look for a range.
