Hi , I think if ever you want to sell this property in the future - you will need to follow Vastu guidelines in the design at this point - otherwise this may hinder resale. Assuming that the architect has followed this and the plan is set - I would suggest you use colours and artwork to create the look that you are after ... Also consider shelving going across the full window wall - this will give you extra storage and also somewhere to grow herbs etc in front of the window - maybe even have a deeper shelf at worktop height and a stool infront of the window ? If you do a picture search on elements that you would like to add - ie kitchen "turquoise accessories" or kitchen "gold" etc you will get lots of inspirational images to help you get an attractive kitchen ... Best of luck with it all ! :-)

So the countertop in the picture is the red color? And the grey is the other color you want to use?

I agree with divadeva. More lights. If you can add pot lights do it. If they're already there add task lighting and up the wattage on the bulbs on the pot lights (replace with LED and you can make them brighter because the wattage on LED is lower for brighter light). If you have all of that add decorative lighting. If ventilation is an issue find a way to move the air around or add air filtration. Maybe the HVAC is deficient. Maybe you can add a HEPA filter instead of the standard one that comes with the unit. Call an HVAC specialist to see if there is a way to boost air flow in the room.

Please consider this reorganization of the spaces which makes the most off the area available. The dining area is moved from the dark interior to share the same area as the living room, across from the open kitchen counter which would serve as a buffet. The black volumes are false columns faced in stone or marble or any other material of your choosing to give the space some girth. This distribution of the spaces gains you a walking closet for the master bedroom. Its ultimate effectiveness depends on your needs. I hope this is somewhat useful.
