Dark sky and clouds

[AntonisKl]

The sky and the clouds are appearing dark to me as you can see in the pictures below. I have applied some post processing parameters but even when I turn them off the sky and clouds are darker than the picture that is in the description of this GitHub project.
Unity version 2018.3.2f1

UPDATE: I managed to fix the problem by changing the parameters "Scattering Coeff" and "Extinction Coeff".
