That’s the way it is supposed to work. There is one gene that determines if the base color is white or blue. The brown and green comes about because of other genes that puts brown with that. Look at it this way:

Base white + no brown = white
Base white + brown = brown
Base blue + no brown = blue
Base blue + brown = green

There are a lot of different genes that can add brown. Which genes are present and how they mix together determines which shade of brown or green you might have. Some people look at it as a white or blue car being painted with a spray gun, but that’s not totally correct. Still, you can usually scratch the brown off to see the base color underneath.

If you crack the egg open and remove the membrane inside you can see that the shell is basically white. I’ve seen some that look a little ivory or pink when I do this, not totally bright white, but that brown outside covering can be scratched off.
