Welcome to the forum, my thought would be to do a skim coat, but I am sure the guys much more versed in this will have some other options.
I used those color samples you sent me on a recent bid, I think they were much easier to use than a fan deck, I hope the HO goes with one of the colors.
We have several members here from Boston that may be able to help you out.
There are painters that do it, I am sure there will be more responses shortly. While you are waiting, why not head over here and share some of your thoughts, color choice has been a hot topic around here lately!
