It is difficult to see with such tiny thumbnail photos but what I see says KEEP them. They look pretty. Maybe just change the countertop and backsplash.

Yes, keep the cabinets as they are. If you want a bit of a refresh you can go from changing out pulls and such or move on to backsplash and counters as boxer pal suggested.

i updated the photos ; ) sorry about that! thanks for the responses so far!

As is

They look to be in great shape and match the LR built-ins. I wouldn't paint them. I agree it's kind of dark though. Consider a lighter countertop, and if you don't have any, good under cabinet lights (LED). They really lighten up a space.

The cabinets look fine to me. I think what you are really lacking is good lighting. Can you get an electrician to install some more lighting, including under cabinet lighting if you don't already have it. I'd put some light directly over the island, either pendants or more can lights.

Your counters are dark too so if you have the budget and the appetite for the work, I'd consider a lighter colour counter and backsplash. I can't tell the backsplash from the current photos.

The Caesarstone site has a visualizer tool so you can find a picture of similar toned cabinets and try out various counter colours on it. It might help you see your kitchen differently. Have a look at Statuario Maximus in the visualizer with your cabinet colour. There are so many choices to try....keep looking until you find something that appeals to you.

In terms of wall paint....the walls look white in the picture. Maybe if you choose a new counter, your paint colour could change at the same time. If you have a small budget for now, then I'd start with lighting and a paint colour change to see if that is enough to get you started.
