I'm amazed you haven't gotten a bunch of comments yet! Painting original woodwork s usually a big topic! I've seen idea books about how to work with natural woodwork, maybe check it out and see if you get any color inspiration? General consensus on this topic seems to be do what you want - it's your house, but if you are thinking of selling anytime in the next few years, try to avoid painting the wood as it can be a selling feature...

Do not paint wood refinish it before you paint it are the doors and trim all in good shape ?

Just looked at numerous 100 year old houses on a real estate sight in North Carolina and the one's with painted trim looked so much brighter, lighter and updated. The one's not painted were kinda tired looking. Each house and woodwork is different though. I think painting woodwork looks fantastic though so paint away!!!

Just move!

I say don't paint, they look gorgeous. Paint the walls white if you want to brighten up the house

I'm in the don't paint camp. I will admit that I did paint in my second home because the majority of the wood was damaged with moisture, and it was easier (and cheaper) to paint than refinish. But I was still young, broke, and didn't know better. I'll bet the current owners cursed me in the months they spent stripping off my paint. Sell your home to someone that appreciates the beauty of the wood and buy what you like, otherwise it may haunt you the way it has me all these years, and years, and years..... ; )

Sometimes sanding down (or stripping) will reveal a wonderful natural wood color. Old varnish has often turned yellow. Afterwards a little colorless stain is all it needs.

Can you work around it to update the look? What colors are you using in there? Are the doors like that in the entire house? Changing the creamy wallcolor to pale grey (with some blue or green in it) can make a huge difference. If all other plans fail, you could paint the baseboards and trims offwhite and leave the doors natural, they're gorgeous and have historical value.

Yes I am also in the dont paint these beautiful doors! use the wall and accessories for colour!

Please just clean it with Murphy soap and polish with Lemon oil . No paint.

Strip the doors, sand then painted with a off white lime paint. Sand the lime down to expose the wood grain you want. Poly with a water based poly so it will not yellow.
