Depending how the kitchen is set up I don’t need all appliances to necessarily match. I am very NOT matchy matchy in the rest of my decor by choice.
If my refrigerator was white and not right next to my stainless steel dishwasher and stove - I would probably be ok with that. Do I want one white, one black, one stainless and one off white……no! 
My dream would be to actually have a colored oven.
