If you can post more pictures of the entire kitchen you might get more specific suggestions.

Here are a few ideas...

agree^ better photos and measurements, budget limitations?

what kind of natural light? explain your preferred style, colors, much more information to receive the best recommendations, please.

can you show the floor? its a traditional door style so changing to white or near white adjacent surfaces will not make a "modern kitchen" but it will feel a lot brighter and add freshness to the space. any updates to lighting can help. do you have under cab lighting?

So helpful. I do have under cabinet lighting but no natural light. So dark & depressing - just so ‘heavy’. Not expecting ‘modern’ but hopeful for NOT depressing.

The only thing that will truly make your kitchen brighter is better lighting. Can you take a picture of the fixture that is in the ceiling?

Then add white counters, white splash, and polished chrome hardware, which will help bounce the light around a bit and add some sparkle. Paint the walls white. I'd get a wood floor.

Consider painting the interior back of the glass cabinet the same as your new wall color. It will make things feel a lot lighter.

This wood floor works with these dark cabinets. Of course there is natural light in here that you don't have. But You can still see how all white is a nice update.

This kitchen also has all white walls, counters, splash, and a wood floor. But, it still looks sad because there is not enough lighting and the light that is there is too yellow. You need 3500k bulbs at least.

If you really update w the white family of surfaces id consider a traditional black and white floor. small sq footage it appears.. this would add a little chic and much better than beige floor for not much expense . On the diag creates a wider feel / you are going to end up w a small stylish kitchen i think youll like a lot. figure out what changes you desire for the budget at hand

A cool floor while traditional….

I would prime the walls and ceiling and look at the space without the wall color.

Change out the light bulbs and remove all the decor. Sample colors you are interested in. Must you keep the floor as is? although dated, a light floor would be preferred to help bounce what light you do have around the room.

Is it that narrow? any more pictures?

Lighting will have the most impact if you are retaining the dark cabs. Recessed 4" 3500K led cans installed 3-6" in from the edge of the counter for task lighting without shadowing. And look at your undercab light output. Led strip lights come with different number of leds per inch. You can get more light by going up to the higher level. I wouldn't do counters, etc. unless you do cabs and appliances. Counter-depth frig, induction range and dw with a possibly reworked configuration.

What color are you suggesting?

Difficult to be precise with colours off a computer as every screen shows a different colour from another. When choosing your tiles, countertop and flooring just make sure the whites are in the same tones. Here are some options:

I would paint the walls and ceiling, replace the backsplash and hardware.

The cabinets are fine, the countertop is nice, and the tile flooring just needs a good cleaning.

I know this isn't your granite, but it gives you an idea of what a light backsplash would look like against your dark cabinets and existing granite. I would look for a simple tile similar color to your floor, but with shine to bounce light around the room. SW Alabaster would be a paint color to start sampling. You'll find the right color once you get started, sometimes it's easier to eliminate rather than choose right out of the gate. Have Fun!

Your backsplash should not be a combination of the 4” subway tile with the pebbled tile on top. One or the other, not both. Replacing them both like the inspo picture Lyn Neilson posted would be a lovely improvement.

I disagree with Lyn. Your counter does not have white/ cream in it like her example.

i agree wth changing the counters and backsplash to a white, but then, what about the floor?

Good observation! Curious to hear answers.

In addition to these other tips, making the inside box of your glass fronted cabinets off white it will lighten things noticeably. Even just the back surface done with contact paper or posterboard cut to size and double sided tape!

Here's a quick example of a darkish color cab with white inside. You can see how much brighter it looks compared to the solid door cabinets.

You could also back the glass with fabric or paint to make it solid white.
