If they are in good shape, I would see no need of replacing them....blue with white cabinets sound great to me. If the new owner wants another color, they can replace them. I think staging a blue and white kitchen would be easy....either with yellow or red accents...or even celery green etc.
Good luck~~

If they're in good condition, I too would leave them. Although not all buyers will like the blue, some buyers would prefer to replace the countertops with something of their own choosing.

I agree with the others. Let the new owners replace them if they want to.

It would depend a bit on what kind of blue they are. Baby blue? Yech. Navy blue? Yes.

As long as they aren't worn or in bad shape I'd leave them. Most people realize when they buy that somethings will need changing to suit their taste.
If it ain't broke, don't fix it.

I don't think it would help to know what color of blue they are. That again goes to personal choice. I agree with the others. Leave them.

Terriks.....Yes, they are a dark blue. They are called Oceana blue from Corian.
Thanks everyone, for your opinions. It would be great to be able to leave the counters. Literally, they look brand new and are in perfect condition.

I have a friend who just put in that color, with yellow cabinets. I thought yuck when she told me, but when I saw them, they were very striking & I loved the look. I say leave them too.
