Your kitchen doesn’t have to stay as one colour. By using two shades, not only does it give you opportunity to reference two colours from your palette, but it lets you change the pace of your scheme.
One way to do this is by picking from the opposite sides of the colour wheel. Green-blue Powder Blue and earthy red Paprika would be two examples, as would Flax Blue and Burnt Sienna or Mustard and Navy.
Another idea is to take one more colourful colour and one neutral. The contrast is still lively, but incorporating a more familiar shade like white or grey helps you to be braver with your cabinet accent colour.
And then if all-over neutrals are more your cup of tea, you can do the same thing by choosing two colours from within each of our core palettes. Silver Birch and Grey Oak for instance, or Shell and Cobble.
