The chrome and stainless steel can vary some too, but usually not as much, and as often as nickel.  To be safe, get samples from different brands and compare the colors, or get all the hardware that you need for  a single room from one manufacturer.  It’s ok if the nickel in one room doesn’t exactly match the nickel in another room.  It only looks mismatched if the different nickel finishes  are right next to each other in the same room.
What kind of new hardware should you install in your updated kitchen? There are so many choices out there it can be overwhelming. Knobs or Pulls? Nickel or Brass? Will you be able to see the holes from the old hardware? Because I am being asked these questions on a daily basis I’ve put together a general guide to updating hardware and have included some of my favorites to share with you.
