Hey bodies I'm back I need you againnnnnnnnnnnnnnnnn
I'm trying to get quiet same result as a render from a great and famous french factory...but I can't

I can't get the same blue color on ground and yellow light on ceiling.
Why? I don't know...I'm using a 100m sphere with texture 200% lum and powered with KrayPhotonMultiplier, exponential 1.4, 1, desaturate shader 50% on floor
can anybody help me get as closed as possible the same result as this great render...?

I am not an expert but i think you need to fix some errors in your scene.
1.- Your sun don´t have streng, i think the inverse distance are low. Try 1200 m
2.- You are using a sphere whith texture how a world sky. You don´t include this on the scene file, but i think is completely blue. You need to use a gradient texture blue-gray or blue-brown or try the fantastic Sunsky plugin.
3.- Change your Area light to a SpotLight and change color to a cream color, no orange or yellow.

Yes I agree with this comments... Sky and sun color and intensity is the key!
