What colors/finishes are your cabinets, countertop, backsplash, & floors? They may have a bearing on what we suggest. However, without more information, if you are going to mix, I would suggest first SS and second black. I think white would just make the off-white look dingy.

I don't think that bisque will be obsolete in the future. The trend seems to be toward more choices. You haven't said whether or not you actually like the bisque. I personally do, and so in your situation I would buy the bisque range. I think it would look best to match the appliances. But if you dislike the bisque, stainless would be my second choice. I agree with buehl that putting in a white range with a bisque microwave overhead will look bad.

Interesting question. My new kitchen has creamy white cabinets. I kept all my bisque appliances because they were less than five years old and they look great with the cabinets. Now, if they ever need replaced anytime soon (hopefully not!), I think I'd look into either bisque or stainless. It seems like there are a lot more choices in stainless than bisque these days. If you decide to go stainless, I think the mix of the stainless and bisque would be fine. Good luck in whatever you decide!

Thanks...I don't mind the bisque, I just had a salesman tell me it wouldn't be around five years from now. There are a lot more choices in stainless, and I do think white would make everything else look dingy. I was debating on a dual fuel...but have never had gas, always electric

If you like the bisque, I'd stick with it. Who cares what the salesman says. If by the time you have to replace the next appliance bisque is no longer available, THEN you can decide on what color to get next. Why fret about it now? That salesman might or might not be right. Even if the manufacturers have specifically told him they are going to discontinue bisque in five years, until they actually do that, no one knows for sure.
