lighting Does diffusion affects the light temperature?

I would like to know if, for ex.;

I use a 3200K light, and in front of it I use a Silk diffusion, it will cast as a, for ex. 4000K light?
If that's right, which is the appropriate way to calculate it?

I was arguing with a co-worker about this and had the doubt.

Thank you
It depends on the diffusion you're using. If it is a truly neutral diffusion, it will not affect the color temperature of the light. If you have a smartphone, you can download an app that will tell you what the temperature of the light is at the subject. You can use that to ballance. Alternately, you can get a color card and balance to that.
