Don’t be afraid to mix cool and warm tones. Appliances are always going to have stainless steel handles, so don’t compromise your design ‘wants’ because you’re afraid of them clashing. Keeping it to two finishes is a safe way to keep the space consistent. For example, if you wanted nickel or brass handles, you could install a chrome tap that will compliment the appliances. Or, match your handles to the tap and keep solely the appliances for the second tone. If your handles and tap aren’t identical twins, it won’t be a problem. Contrast is actually the key here, despite it being the scary bit. Incorporate it as part of the design.
