Difficulties in defining a new trans material - shoji paper

Hello everyone, I am trying to create a material that has the same characteristics as shoji paper with honeybee to do some lighting analysis. I am having difficulty setting the values for the HB Translucent Modifier 3 component. In the end I would like to obtain a material with the following RGB(230, 223, 211) and a light transmission factor of 50%. The transmitted light must only be diffuse, not direct.
Can anyone help me out?
