I finally reproduce the issue
.blend attached

I thnink there's something i'm doing wrongly
Yes, you have been misguided by the Color node. I think you don't understand what it exactly do. It transfer only color not it's saturation, so the saturation of the color will be ignored.

Blend4web and that kind of thing.

Thanks again for your quick reponse, i try to finish this point before the week end.
Now i understand well.

So maybe i'm on the wrong way, my purpose is to change an object color by javascript (color given by a colorpicker HTML).
Any advice?

See this code example to get an idea how to change material params in runtime:

Hi

Hi.

Be sure that your object is dynamic (enable the Force Dynamic Object property on the object properties panel). Also take a look at this example.
You need the following code line:
m_mat.set_diffuse_color(cube_diffuse_color, "mat_diffuse_color", [0.5,0,0]);


And don't forget, that r,g,b values should be < 1 and > 0
