Anyone?

What warm colors do you like? I agree that it looks too sterile, being mostly white. Here are some color suggestions:

They used a pretty soft green for the backsplash. A soft green paint would also do the trick!

I know you said light colors but red would really warm the kitchen up a lot!
I also love this bold, orange color!
Love the aqua color!
I stayed away from blues and gray since most of them will just make your kitchen look colder. Whatever color you decide, I suggest you buy paint samples, paint a decent sized section on your walls and look at the paint a few days to make sure it's what you want. Look at it in both sunny and cloudy days along with how it looks under your kitchen lights.

I'm no use. I actually like it a lot as is and would just add some texture (baskets, seagrass, wood) or a few colored kitchen accessories (utensils not in black), clock, fruit bowls, and plants. I mean those fruits you have there now just pop. And some large format art in your eating area. Maybe a runner.

I just love the low backsplash on the perimeter and just behind the range. I'm assuming you have googled deVol kitchens.

Are you in Europe? Could you tell us more about this kitchen? I just really like it!

and links from there.

I'm thinking maybe a sage green might work. I've tried a variety of warm greys and they just aren't working. I like the white when we have the lights on but in daylight it feels too stark.

Just can't find a paint I like!

this may be too dark for all round
