I have seen that too but I don't believe it to be a fault or that the colors actually shift.

However it is an optical illusion, the quarterpanel meet the door at an angle making the light come in in two different angles. So the reflection of light, giving your eyes the color, have different reflection angles making the slight difference in hue you will see.

Try to look from above at the door gap and you will not see any difference.
