TCS34725 Color Sensor RGB Readings

I'm very new to using arduinos and sensors, and I just bought the TCS34725 for a project. I'm trying to use the principles of the Litmus test to sense pH via color and a universal dye. When I use the sensor and starter code from adafruit, my RGB values are far beyond 255. I was wondering if I need to calibrate the sensor or use some code to get recognizable RGB values?

Thank you!

It looks like this sensor works similarly to the TCS230/3200 but with an I2C interface. If that is the case this blog post may be helpful.
