In the photos all the colors seem to appear grayer/bluer than I would expect from how the colors normally appear. That does point to a lighting problem. Not enough natural light combined with not enough indoor light, and maybe not the right color temperature of indoor light. If you have LEDs in your ceiling fixtures, it could also be a problem with poor color rendering (LEDs vary a lot in their color rendering index, or CRI--look for 90 or higher). If you have LEDs, I would check the lamp characteristics first. If the color temperature is above 3000, or the CRI is below 90, that could be your problem. I think Herbflavor may be right though: Your current lighting seems in adequate. Your kitchen would probably benefit from more lighting fixtures (recessed cans) and more total lumen output. Warmer color temperatures (2700-3000K) should help bring out the yellow in the Ivory Lace.

I agree too early to even begin to decide wall color . IMO all those shelves need to go I see something that would always feel like it was going to topple on my head .Do you need an office ? If so what do you need in it? IMo rip out what is there and take some pics and also post a to scale floor plan of the space with info as to what you need in there . Once tha is decided then you pick wall color.

It's hard to tell without the cabinet doors on but from what I see I'm thinking you should stay in the grey category

so much depends on the size of the kitchen, how many cabinets fill the space, and the flooring and countertop options. A few photos would help, add in comments, or edit your post.
