I think it should match the appliances/finishes in the kitchen :) We are having one built that matches the cabinets, but we are starting from scratch. In your shoes, I would buy black.

Wood hoods are available. You might have to do some googling to find what you want or someone to build it and stain it to match your cabinetry. We had a wooden hood for years made by Wood-Mode and it was visually OK -it matched the cabinetry. The Thermador fan in it was worthless, though. Hard to clean the wooden cherry Wood-Mode hood, though, because anything that was a strong degreaser also weakened the finish. Check with your cabinetry manufacturer, even if the cabinets are older. They may still make something.

Black hoods - consider that black does show grease easily and looks dirty fast. Think of how spots show fast on black cars. Also sucks up light at eye level. If the space is really well-lit, the impact is less.

Our hood does not match anything else in the kitchen - it is copper - and it makes a statement as something different. It is trimmed with stainless steel, partally matching the cook-top and wall-oven. People really like the hood when they visit.

I'll not ever forget reading the book called, "How to Not Act Old" or something like that. Funny read. One of the caveats in the book is, "Don't be matchy-matchy." You know, wearing pant suits that are all matchy matchy, dressing in outfits with hubby that are matchy matchy. Well, some people do like to do matchy matchy with clothes and such - - I've done that myself - - but it is OK to not be matchy matchy unless you want to do it that way. No one will throw the Kitchen Design for Dummies book at you.
