I am making a model of a spacecar and I wanted something at the back emitting blue light. So after doing that i notice that the blue light has spread to the car with a different node, so i delete the part that was meant to emit blue light and the error is still there. Also the “doors” have the right colour because it is a different object.

As noted the doors are the right colour and the material node is the main car

Not enough info supplied.

Is the material use for the blue light the same material applied to the blue faces in you image ?

Well that solved it. The faces was not the same material as the object.
