3 rooms full

I have been put in charge of a project to build out a facility that has three rooms for audio/video production of "fireside chats", small group discussions and a classroom setting - talking head. The first room is a living room enviornment with a 4' x 6' window on one wall. Any suggestions on colors of furniture that work better than others? Need ighthing suggestions (portable or fixed in the 10' 4" ceiling or both) The second room is a board room setting with no windows. The last is a classroom area with two 4' x 6' windows and a double glass door entering into it. As for the windows and doors and suggestions on dressings to block or modify ambient light? Same question again, portable suggestions or fixed suggestions.

I have read through many of the threads and found some information, but it is mixed and in different applications, green screens, etc. So I did try.

Thanks ahead of time for any responses, usable or opinions on my post and typing ability or master or lack there of the english language. May all your light shine where it should.
