Looks like you could benefit from some better lighting in there. if you are able, the floor being lighter might help too, something in a cream color. under cabinet lights or maybe a backsplash that is reflective like mirrored or glass.

Your dining furniture is quite formal. Just add a bowl of flowers or fruit to the top. roman shades on the window will be the best due to the radiator & a hanging light fixture (after affixing the hanging light bulb to a proper connection). Add a runner rug for additional color & a piece of art above the table.

Are you painting or replacing anything?

Not changing floor or anything ... But I feel like I need color.. And the kitchen is open space and goes into hallway and living room

For lights .. Something like this ?

Look to your LR for color. It will help to unify the space. Just to add, that floor is a considerable color-setter in that room so if your LR clashes with it, try to find a color that works with both.

A great site for looking at color palletes is design-seeds.com

I try to inspire myself from different pictures But i have to work with This Floor and i'm not happy :( Need help exactly what i have to do :)

Mattress ticking would like nice w your floors. It is available on ebay, if you have trouble locally, and could be used for your window treatment. You may find similar looks for kitchen towels. Patterns vary:

Maybe some artwork with color above the table and a pretty roman shade with a fabric with color that makes you happy and coordinates. From there you can add any accessories in a color pulled from those. If you don't like the floor you could cover a majority with a decorative rug. What colors do you gravitate to or what colors make you smile? Floral, stripe etc?

Should I change the walls color in kitchen instead of white ?
