Please, oh, please don't paint the hinges white. It will make your whole paint job look like a hack job. Look at gate hardware if you feel the need to replace them.
You'll find this hardware around for cabinets, but it's no longer commonly found.

Another option would be to use something like the Ce Ce Caldwell paints that adhere well, and perhaps gilding them with something in a dull metallic.

I can actually see these hinges looking pretty nice on a white/cream colored cabinet. It might be a challenge finding handles (I'm not a knob person; they're always coming loose), so you might consider keeping these, but moving them down to a more modern level.

What I really like about your cabinets is they're inset. Being a forced DIYer, I'd change the door and bottom drawer a tiny bit. I'd shorten them. Then, I'd put a stile at the bottom of the uppers that's the same width as the rails on the side. For the drawers, I'd make it the same width all around. It would also modernize a traditional look to traditional vs. era look. Does that make sense?

From what I can see, these look custom and are probably well made. What's on the other side of the kitchen?

Those are pretty cabinets. Are they early 1950's? Do you want to keep a vintage look for your home or are you trying to modernize? Do the drawers stick or pull out smoothly.

If keeping vintage, I'd clean & polish them and not paint. If you are trying to totally change the look of your kitchen and home, I think you're going to have to do as CEFreeman suggested. You'll have to shorten all the doors and add a bottom rail between the stiles. Then on the hinges, since they are inset, you can change out to a different type for inset door, not visible from the front. But that will only look good if there aren't indentions from the current hinges.

Do you have any photos with a door open?

Thank you! I now agree with not painting hinges white!
Maybe I'll keep everything and lower the handles on the doors. CEFreeman, do you have an example of the change you'd suggest? I'm not that familiar with door cabinet terminology.

Kenfused, look at some pictures of inset cabinets, and you will see that the frame (that yours have on the sides and top) run across the bottom also. She suggests shortening the door so you could put that bottom piece across your cabinet, and the frame will run on all four sides of your doors.

This is going to reqire moving those hinges, though, so they stay the same distance from the top as they do from the bottom.

They are quite pretty. I, too, like the hinges.
