First, change your lighting. That's your biggest issue with yellow. You want +3000 Kelvin, with a CRI index as close to 100 as you can find.

Sorry I do not understand your question. There are a few typos.

I am seeing a nice kitchen with a wall color that goes well with the window treatment, cabinets, countertops and backsplash.

I don't see any bold yellow. Even your lighting is not showing as exceptionally yellow on my monitor.

Maybe if you can tell us what exactly is bothering you with the look of the kitchen we can provide better guidance.

K values (Kelvins) of light bulbs can make a difference, but without knowing what you have that may or may not be an issue.

As long as yours are in the 4000-5000 range you really are not adding any yellow.
