Is this for you or for resale?

Uppers and lowers with arches --- painted white.

If it's for yourself, you could paint a color (blue, gray, green) or go two-tone. And perhaps a moveable island.

Yes, the beauty of painting cabinets is they could be any color you want! Think about your personal style and how you feel about color, then do some cruising on sites like houzz.com.

But, as mentioned, if this is for resale keep it classic and neutral. :o)

Those look a little nicer than builder grade orange oak, like maybe maple? The nice range hood also tells me these are a nice grade of cabinetry.
Maybe you should paint the walls a light color first and see if that changes your perspective. It's going to take some primer to cover that red first. Something neutral like Kilim Beige would work for the walls.
I love white cabinets, but pretty wood is nice too, and lightening up the walls would save a ton of time and money. Please post pics if you paint the walls first, and let us see how it changes things.
Please also consider changing out that fluorescent light box. Those can really throw off a room's color. Can you post a closer pic of the cabinets and counter tops?

Here is a kitchen with similar cabinets and beige wall color. You can skip the backsplash and just do the beige paint. Even your green counters would go with this.

And one more, just to give you an idea of how wall color can make a big difference. For a tight budget, this is an easy, quick fix.

Yes, maybe start with cleaning the cabinets and reevaluate. However, if you keep the cabinets as is, the appliance color really doesn't work.
Paint them, too, get skins (fridge, dish washer), or replace?

Your kitchen looks a little dark, not sure if its just the photo. I'd do them a creamy white, it would brighten the whole room up. I've seen some beautiful colored painted cabinets on this site, a light blue and a yellow one comes to mind. You could paint them in color, or you can do the uppers white, and use color on the bottom. That might work better with the white appliances..

I plan on painting the walls in Behr Colliseium Marble or similar. The appliances will be upgraded to stainless. New formica also.
The cabinet color now is too orange for me. I was thinking of staining the cabinets black.

Staining with gel stain is a lot easier than painting; but I would try an inconspicuous side first. Do you know what kind of wood this is?
