now I want to copy the photo with Indigo.
distance of the television camera to the fund of the cube 68cm.
I don't know the lamp.

hmmm...
as the internal colour of that box is white, I guess, you used the wrong whitebalance for your cam: you used sunlight or equal energy, or such, but not "A" (lamp / indoor light / ...)

I guess, your tonemapping is way wrong...
the shadows are weaker, than the model ones...
paper has ~0.85 pure white, you know?
If you use wood, you also can use the correct colours

blue or green and red
And you may ask, which colour that would be EXACTLY,

should be possible
It looks quite nice and quite simmilar

just add a floor plane, to also get that light

ok

try to get the whitebalance of your cam correct, then

if it's still the same lightsource, you need "indoor" or "artifical light" or such a white balance...
my camera has it called "artifical light"

Or simply set your WB in kelvins - looks like you're shooting ~3000 degree light (incadescent) and using a sunlight wb setting (~5600 k)

yes, auto-whitebalance would be a good idea, too.
