Normal colors of "Face normal shader"

[linkoboy]

Hi,

For a personnal project I would like to make "normal" sprites for 2 sprites for a 2d rpg game.
I've found an interesting post (from 2012) :

I'would like to have same colors for the normals in wings 3d like in this picture :



but I've have "RGB" colors like in the attached image (sphere.png)

Is there a way to have the same colors in the viewport that in the post I've found (from 2012) ? (I use 1.5.4 version)

Regards
