render albedo (color passe without shadow) I am trying to render the albedo of a mesh with a material, I have managed to get a flat render without lights and shadows by using the diffuse color passe, but the color are not the same as the one used in the material of the mesh.

Here is my setup: 


3D view:
A sphere (here you can see his material thanks to the viewport shading set to material) and a light (to test if there are shadows in the render
UV / Image:
Each face of the sphere is unwrapped on that square with two color

Shader node:
Render layer:
the passes I have checked

Compositing node:

Result:
As you can see the color are not the same as the one of the UV/Image



Here is a comparison between the color of the image I have used to texture the mesh (on the left) and the color I get from the diffuse color passe (on the right)

Does someone know how to fix that problem or why the color shift ?
As Leander show in the picture of his comment there shouldn't be a problem with the passes or the nodes I have used and how I have connected them.

As hatinacat2000 suggest, I get better result by setting the color space to linear



Here is the texture on the left and the render of the albedo on the right a bit
better but not the same:



In fact the color of the albedo where shifted because of the High contrast setting (in the Look of the color Management), by changing it to none The color of the albedo are the same as the one of the texture
