(We used much more colorful language.)  

New wood and new drywall must be primed, i.e. 2 coats or 1 coat of primer and 1 coat of finish color.

Netural colors sell best.

the color seems a bit washed in the photo it is actually a pretty glass tile with a stone frame

@Robert Conroy Those basement systems when I looked into them were almost the same price as a local basement remodeler without the ability to easily make changes in the future(which doesn't matter as much to you I realize).Personally unless it is a really bad DIY job or your target price range is high I would paint the paneling a light beige color to brighten it up put down some new carpet from Home Depot without padding (~$0.69/sq ft + $150 install from a local installer from my last basement job) and call it good.

Even if they want rooms different colors unless you have neutral colors you will have the rooms the wrong color.

The browner the color, the longer it lasts.

The good hard working men and woman that have a challenged work history or perhaps have a not so colorful background with the criminal justice system.  

Everyone,Do yourself a favor and make sure you check out the contractors with a fine tooth comb.

If you go the solid surface route, get a very light color - white or similar.
