3d view oriented on section

[kubbah]

in a section oriented 3d view I see that the split floors are blue
I can't change the reason for the section

Can you help me?
Thank you.

I also noticed that passing from a 3d view oriented by view cube
at a section oriented view, the volume that had some transparency before, now has a different transparency.. .

to change the color and material of the low detail, you have to go to the material tab and change what has the name "poche", is that associated by default to low detail when sections with the section box.
the different transparency of the volume depends instead on the default light.
