Calibration is Needed

Today I plugged in the the GLOBE and it wasn't recognizing any of the colours properly. I tilted the ball slightly and it is doing a lot better, but I shouldn't have to worry about getting the ball at the exact angle needed to get it to work. Now I have to figure out a way to calibrate the reference colours for the colour detection, or else it just won't work consistently.  

I figured out that the insert message does work for updating the the [coll]. The only thing is the coll then grows to be very big and long because the former messages does not go away, they just get pushed farther down in the coll while the updated messages take their place in the list. I don't know if there is a maximum size that a coll can be, so every once in a while I should open the calibration text file and delete the extra lines. Or have it always open to a default with only 7 list items before calibrating.
