I became familiar with Northwest paint, because they are the only outlet for Devoe paint in the area. Our builder chose Devoe paint throughout our house, and when we have done touch ups and other minor projects, we have always gone to Northwest Paint.
They can match any paint you have if you provide a sample to them.
Devoe paints are divided into warm and cool tones. This allows even the novice to choose paint colors that go well together.
