Speaking of trends ...
The latest design that appears on Pinterest and elsewhere features dark floors and white cabinets. It's very attractive.
Most kitchens look like caves because of all those cabinets in a confined space. Space left over is usually one window.
Lighter colors certainly help - especially at the time when a home is sold. I often recommend sellers spend some money on paint and use neutral colors. But the color and even type of paint can be very important to the room to be painted. There is painting advice to be found on the Internet. And, of course, you can talk to the sales people where paint is sold, like the hardware store. In the real estate profession, you get to see more than a few homes that are not at their best - as say when the owner elects to turn off the power. Dark doesn't not sell well.
Contemporary homes with kitchens opened into a TV/play area generally feature several windows that admit that all important sunshine.
Of course, design can be enhanced with the right lighting.
If you're really in love with dark cabinets, I won't be the one to discourage you. But be advised the kitchen often weighs mightily in the decision to buy. You can still justify your whim. If you plan to stay in your home more than five years, you may be changing the look after a time, anyway.
Enjoy your new home!
