Identifying specific colors with a color sensor is not as simple as pointing the sensor at a color patch and taking a reading.  There are many factors such as distance, field of view and ambient lighting conditions that can affect readings.   Adafruit forum member systembolaget has developed a system capable of quickly and reliably identifying many different colors and has put together an excellent tutorial on the subject.
