you got Cyan. Somebody may have slapped the firmware for the black onto the device. Or somebody took a black L920 and changed the housing to blue (e.g. mine is a chameleon).
and there is still the chance that a blue L920 shows Black.
product codes and colors: this is just for America. there are other codes for other regions.
059L848 NDT AMERICA ATT Black
059N5T3 NDT AMERICA ATT White
059N5T5 NDT AMERICA ATT Yellow
059N5T7 NDT AMERICA ATT Red
059N5T9 NDT AMERICA ATT Cyan

Pull the SIM card out and tilt the phone so that the SIM tray slides out (metal). Your product code will be printed on a label along with the IMEI number.

Or download Nokia Care Suite and connect the phone (under Product Support Tool). It will display the product code.
Just checked mine. It is indeed on the metal sim tray (see video above). It's tiny tiny font and you need a magnifying glass to read it.
