Taillights

got an Omega und now the mid reflector of catera. the Omega outside taillights seem to be darker then Catera´s. Have anyone a pic of a broken taillight where i can see the reflector? Or can someone explain reflectors position? same releflector as in the mid?

look at the picture: the higher part (grey) is the same colour, when i look from side. If i stand in front off i see different colours...
